Available in PDF, EPUB and Kindle. Book excerpt: About ten years after the publication of the Second Edition (1973), it became apparent that it was time for an up-date of this book. This was especially true in this case, since the subject matter has traditionally dealt mainly with the structure, properties, and technology of the various elastomers used in industry, and these are bound to undergo significant changes over the period of a decade. In revising the contents of this volume, it was thought best to keep the orig inal format. Hence the first five chapters discuss the same general subject matter as before. The chapters dealing with natural rubber and the synthetic elastomers are up-dated, and an entirely new chapter has been added on the thermoplastic elastomers, which have, of course, grown tremendously in importance. Another innovation is the addition of a new chapter, "Miscellaneous Elastomers," to take care of "old" elastomers, e.g., polysulfides, which have decreased some what in importance, as well as to introduce some of the newly-developed syn thetic rubbers which have not yet reached high production levels. The editor wishes to express his sincere appreciation to all the contributors, without whose close cooperation this task would have been impossible. He would especially like to acknowledge the invaluable assistance of Dr. Howard Stephens in the planning of this book, and for his suggestion of suitable authors.

Download or read book Synthesis and Characterization of Poly alloocimene b isobutylene Thermoplastic Elastomers written by Attila Levente Gergely and published by . This book was released on 2014 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyisobutylene due to its unique properties, such as exceptional chemical, oxidative and thermal stability, low gas permeability and biocompatibility (bioinert), is a widely used material in applications ranging from oil additives to biomaterials. The objective of this dissertation was to study the copolymerization of alloocimene, a renewable monomer, and isobutylene under the traditional butyl rubber polymerization conditions: H2O/AlCl3 initiating system in methyl chloride solvent at -95 °C. It was our hypothesis that polyalloocimene would lead to improved filler interaction. Our work led to the discovery of the first two-phase (emulsion) living isobutylene polymerization system, solving the problems associated with solution living isobutylene polymerization systems: the use of unique and commercially not available initiators, expensive coinitiator at high concentrations and poor heat transfer due to the high viscosity of the reaction mixture even at low polymer concentrations (15wt%). High molecular weight copolymers, Mn = 200,000 to 400,000 g/mol, with molecular weight distribution of [Uppercase D with a line] = 1.5 to 2.1, were prepared containing 9 to 30 wt% alloocimene at 80 to 90 % conversion. The copolymerization of alloocimene and isobutylene was found to be living up to 40 % conversion, or 6.5 minutes, resulting in a diblock polymer structure, consisting of a polyalloocimene-rich first block and a polyisobutylene second block. Tri- and tetrablock copolymers were prepared by sequential monomer addition technique. Both di- and multiblock structures showed thermoplastic elastomeric properties. This is the first example of a diblock copolymer thermoplastic elastomer. This is also the first copolymerization system allowing the preparation of tri- and tetrablock copolymer polyisobutylene-based thermoplastic elastomers using an inexpensive polymerization system. Diblock copolymers showed outstanding reinforcement with carbon black: the ultimate tensile strength increased from 2-6 MPa to 10-14 MPa at 60 phr (37.5 wt%) loading. The tensile strength of tri- and tetrablock copolymers also increased upon carbon black reinforcement. The ultimate tensile strength of a tetrablock copolymer having Mn = 347,000 g/mol and containing 23.7 wt% alloocimene increased from ~14 MPa to ~22 MPa upon 45 phr (31 wt%) carbon black loading. Silica reinforcement of a triblock (Mn = 205,000 g/mol, 28.2 wt% alloocimene) copolymer increased the ultimate tensile strength by ~50 %, to ~18.5 MPa, using 15 phr (13 wt%) silica loading. The Payne effect in carbon black loaded triblock copolymer compounds was investigated. The dynamic fatigue properties of di-, tri- and tetrablock copolymers and their carbon black composites were investigated using the hysteresis method. The neat diblock copolymers broke premature during the dynamic creep test conducted at 0.51 MPa stress, whereas the tri- and multiblock copolymers showed 144 to 170 % absolute dynamic creep respectively. Reinforcement by carbon black led to a two orders of magnitude decrease in the absolute dynamic creep. Curing of poly(Allo-b-IB) tri- and tetrablock copolymers were investigated using sulfur- and peroxide-based systems. The new thermoplastic elastomers showed similar curing as well as permeability characteristics as halobutyl rubbers. A peroxide curing recipe was developed for poly(Allo-b-IB) multiblock copolymers, indicating no polymer degradation during the curing process.

Download or read book Rubber Compounding Ingredients Need Theory and Innovation written by C. Hepburn and published by iSmithers Rapra Publishing. This book was released on 1997 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of rubber compounding may be essentially defined as providing optimised performance and processability, generally at minimum cost, by the incorporation of non-rubber ingredients. Optimised performance in this context refers not only to mechanical properties but also, for example, resistance to bacteria or particular chemicals. In some applications a rubber may also need to be coloured, or bonded to another material, and further ingredients may be required. For many years, rubber compounding was largely empirical and frequently described as a black art. Today it is practised predominantly on the basis of scientific principles elucidated over years of study and is still the subject of intensive research. In this new report Claude Hepburn reviews the following range of compounding ingredients, considering the range of materials available, their particular actions and recent interesting advances: Process and extender oils; Process aids and surfactants; Coupling agents and adhesion promoters; Fire retardants, bactericides and blowing agents, colourants and odourants. An additional indexed section containing several hundred abstracts from the Polymer Library provides many more examples of novel materials and their applications.
