This book was released on 1975 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six characteristic types of polyethylene terephthalate (Mylar) films were studied by x-ray diffraction techniques. The degree of crystallinity, extent of preferred orientation, crystallite sizes, and paracrystalline disorder were evaluated. The tensile properties were measured in directions parallel and normal to the trace of the optic axial plane as well as in the machine and transverse directions of stretch. The influence of crystallite orientation on the mechanical properties is discussed. The exceptionally high strength in the machine direction of type 142T film may be associated with the high degree of orientation achieved by a two-way stretch followed by a post-stretch in the machine direction. The balanced, physical properties in type 1000S film are likewise attributable to the presence of two-way stretches in mutually perpendicular directions. The influence of crystallinity was masked by the anisotropic disorder arising from varying degrees of preferred orientation. The techniques employed are indicated to be applicable to other polymeric materials.

Available in PDF, EPUB and Kindle. Book excerpt: The study of the relationship between the structure, morphology and properties of polymer films has significantly progressed in recent years through the use of a number of phyiscal techniques - some new and some old. These methods include small and large angle x-ray diffraction, bire fringence, light scattering, infrared dichroism, fluorescence polarization, light and electron microscopy and interferrometry. This collection of papers, most of which were presented at a symposium at the Boston American Chemical Society Meeting in April, 1972, represent a collection of recent studies using many of these methods by some of the leading scientists in their fields. It is evident that these various techniques permit the study of various aspects of film structure such as crystal structure and orientation, amorphous orientation, the interrelation of crystalline and amorphous regions in lamellar, fibrillar, and spherulitic superstructure and the relationshi. p of these structural variables to the mechanical and optical properties of the films. Film structure is sufficiently complex that a complete understanding of the relationship between structure and properties will come from the employment of a combination of several of these methods. vii CONTENTS Optical Studies of the Morphology of Polymer Films ••• • • 1 Richard S.

Available in PDF, EPUB and Kindle. Book excerpt: This collection of research and review papers is aimed at depicting the state of the art on the possible correlations between processing variables, obtained structure and special properties which this structure induces on the plastic part. The extraordinary capacity of plastics to modify their properties according to a particular structure is evidenced for several transformation processes and for many applications. The final common goal is to take profit of this peculiar capacity of plastics by inducing, through a suitable processing, a specific spatial organization.

This book was released on 2017-10-12 with total page 1382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook provides an exhaustive description of polyethylene. The 50+ chapters are written by some of the most experienced and prominent authors in the field, providing a truly unique view of polyethylene. The book starts with a historical discussion on how low density polyethylene was discovered and how it provided unique opportunities in the early days. New catalysts are presented and show how they created an expansion in available products including linear low density polyethylene, high density polyethylene, copolymers, and polyethylene produced from metallocene catalysts. With these different catalysts systems a wide range of structures are possible with an equally wide range of physical properties. Numerous types of additives are presented that include additives for the protection of the resin from the environment and processing, fillers, processing aids, anti-fogging agents, pigments, and flame retardants. Common processing methods including extrusion, blown film, cast film, injection molding, and thermoforming are presented along with some of the more specialized processing techniques such as rotational molding, fiber processing, pipe extrusion, reactive extrusion, wire and cable, and foaming processes. The business of polyethylene including markets, world capacity, and future prospects are detailed. This handbook provides the most current and complete technology assessments and business practices for polyethylene resins.
