This book was released on 1978 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The miscibility of homogeneous diblock copolymers of 1-4-polybutadiene and cis-1-4 polyisoprene with either or both of the corresponding linear homopolymers was found to depend upon the relative lengths of the block segments and upon the coordinates of the binary or ternary mixture on the appropriate triangular composition diagram. Evidence from a variety of experiments was used to draw overall conclusions regarding the location of the diblock in these blends and its influence on physical properties.

This book was released on 1981 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure and mechanical properties of a series of polymer blends and block copolymers comprised of medium cis 1,4-polybutadiene and 99% 1,2-polybutadiene have been investigated. Thermal properties (DSC) were determined at two levels of radiation crosslinking and for various sample preparation procedures (solvent and thermal history). Dynamic mechanical spectra (3.5 Hz) were measured over temperature range from 180 to 310K. Transmission electron microscopy was also used for establishing the number phases and the domain size and geometry in the heterogeneous materials. Stress-strain curves were determined for the various samples as a function of crosslink density and casting solvent. Equilibrium swelling ratios were measured for each specimen at the same radiation dose in a good solvent. Swelling values were also obtained in a series of solvents for the parent homopolymers and for a diblock copolymer containing 45% 1,2 polybutadiene.

This book was released on 1983 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of blends was prepared form homopolymers and diblock coploymers of 1,2-polybutadiene and 1,4-polybutadiene. Samples were studied by dynamic mechanical analysis and transmission electron microscopy to determine whether a homogeneous or heterogeneous morphology existed. Although blends of the homopolymers exhibit phase separation, inclusion of an appropriate amount of a diblock polymer can lead to a homogeneous morphology. The materials examined covered a wide range of molecular weight, composition, and diblock copolymer fraction in the blend, enabling an experimental phase diagram to be determined. These findings are compared with current theories of phase behavior for blends of diblock copolymers and homopolymers. (Author).

Download or read book Introduction to Polymer Rheology and Processing written by Nicholas P. Cheremisinoff and published by CRC Press. This book was released on 2018-01-18 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Polymer Rheology and Processing is a practical desk reference providing an overview of operating principles, data interpretation, and qualitative explanation of the importance and relationship of rheology to polymer processing operations. It covers full-scale processing operations, relating industrial processing operations and design methodology to laboratory-scale testing. Hundreds of design formulas applicable to scaling up the processing behavior of polymeric melts are presented. The book also provides a "working knowledge" description of major rheological test methods useful in product development and includes a useful glossary of polymer and test method/instrumentation definitions. Lavishly illustrated and featuring numerous sample calculations and modeling approaches, An Introduction to Polymer Rheology and Processing is a "must have" book for polymer engineers and rheologists.
