This book was released on 2013-10-22 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Effect of Molecular Orientation on the Mechanical Properties of Polystyrene presents the results of a study that investigated the effect of molecular orientation on the mechanical properties of polystyrene. Oriented sheets of two commercial homopolystyrenes (PSA and PSB) differing in molecular weight, rheological and glass transition temperature properties were prepared by sheet extrusion and drawing. The properties of the resulting sheets were examined at seven different laboratories in Europe. The study focused on length reversion ratio, birefringence, orientation stress, shrinkage stress, and various mechanical properties such as rupture stress and strain, the specific energy of rupture, and sonic modulus and relaxation modulus. Impact behavior and environmental stress cracking behavior were also evaluated. One of the findings was that oriented polymers subjected to lateral strains can develop catastrophic crack growth when immersed in an active liquid. The onset of the cracks depends on the lateral strain imposed as well as the degree of orientation. PSB was more resistant than PSA. This monograph should be a useful resource for chemists.

Download or read book Rheology written by Giovanni Astarita and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 749 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the VIIth International Congress on Rheology, which was held in Goteborg in 1976, Proceedings were for the first time printed in advance and distributed to all participants at the time of the Congress. Although of course we Italians would be foolish to even try to emulate our Swedish friends as far as efficiency of organization is concerned, we decided at the very beginning that, as far as the Proceedings were concerned, the VIIIth International Congress on Rheology in Naples would follow the standards of time liness set by the Swedish Society of Rheology. This book is the result we have obtained. We wish to acknowledge the cooperation of Plenum Press in producing it within the very tight time schedule available. Every four years, the International Congress on Rheology represents the focal point where all rheologists meet, and the state of the art is brought up to date for everybody interested; the Proceedings represent the written record of these milestones of scientific progress in rheology. We have tried to make use of the traditions of having invited lectures, and of leaving to the organizing committee the freedom to choose the lecturers as they see fit, in order to collect a group of invited lectures which gives as broad as possible a landscape of the state of the art in every relevant area of rheology. The seventeen invited lectures are collected in the first volume of the proceedings.

Download or read book Micro and Nano Fibrillar Composites MFCs and NFCs from Polymer Blends written by Raghvendra Kumar Mishra and published by Woodhead Publishing. This book was released on 2017-06-19 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micro and Nano Fibrillar Composites (MFCs and NFCs) from Polymer Blends is a comprehensive reference for researchers, students and scientists working in the field of plastics recycling and composites. The book aims to determine the influence of micro and nanofibrillar morphology on the properties of immiscible blend systems. Chapters cover micro and nanofibrillar composites based on polyolefin, liquid crystal polymer, biodegradable polymers, polyester and polyamide blends in various industrial application fields. The book brings together panels of highly-accomplished experts in the field of plastics recycling, blends and composites systems. For several decades, plastic technology has played an important role in many industrial applications, such as packaging, automobiles, aerospace and construction. However the increasing use of plastics creates a lot of waste. This has led to restrictions on the use of some plastics for certain applications and a drive towards recycling of plastics. More recently, microfibrillar in-situ composites have been prepared from waste plastics such as PET/PP, PET/PE and Nylon/PP as a way of formulating new high performance polymer systems. This book tackles these issues and more, and is an ideal resource for anyone interested in polymer blends. - Provides information on MFC and NFC based polymer blends that have been accumulated over the last 25 years, providing a useful reference - Adopts a novel approach in terms of understanding the relationship between processing, morphology, structure, properties and applications in micro and nanofibrillar composites - Contains contributions from leading experts in the field from both industrial and academic research

Book excerpt: The seventh edition of this classic reference work once more provides a comprehensive overview of commercially available plastics materials. Bridging the gap between theory and practice, it enables scientists to understand the commercial implications of their work as well as providing technologists with a theoretical background.Since the previous edition, several new materials have been announced. Many of these materials result from metallocene catalyst technology. In addition, developments also continue with condensation polymers with several new polyester type materials of interest for bottle-blowing and/or degradable plastics. New phenolic-type resins have also been announced. As with previous editions, an explanation of the properties of these new materials in terms of their structure and morphology involving the principles laid down in the earlier chapters is presented.

Download or read book Selection of Polymeric Materials written by E. Alfredo Campo and published by William Andrew. This book was released on 2008-03-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today engineers, designers, buyers and all those who have to work with plastics face a dilemma. There has been a proliferation of test methods by which plastic properties are measured. The property data measured by these test methods are not identical and sometimes have large differences. How are engineers, designers, buyers going to decide the type and resin grade and their property data? Which are the valid test methods? The right plastic property data are the difference between success and failure of a design, thus making the property selection process critical. For the first time this book provides a simple and efficient approach to a highly complex and time consuming task. There are over 26,000 different grades of polymers and millions of parts and applications, further adding to the difficulty of the selection process.Selection of Polymeric Materials steers engineers and designers onto the right path to selecting the appropriate values for each plastic property. A large amount of property information has been provided to teach and assist the plastic part designer and others in selecting the right resin and properties for an application. Various standards including ASTM, ISO, UL, and British Specifications have been discussed to help the readers in making sound decisions - A simple and efficient approach to a highly complex and time consuming task - Allows engineers to select from various standards including ASTM, ISO, UL, and British Specification - Presents information on properties such as tensile strength, melt temperature, continuous service temperature, moisture exposure, specific gravity and flammability ratings - Tried and true values narrow myriad choices down quickly for readers
