Compatibilization of Blends of Crystallizable Polybutadiene Isomers by Precipitation and by Addition of Amorphous Diblock Copolymer

Abstract

A brief summary of the research on compatibilized polymer blends is presented. Of particular significance is the model system of crystallizable polybutadiene isomers: trans 1,4 polybutadiene and syndiotactic 1,2 polybutadiene. Appropriate blending procedures, rapid precipitation from solvent (sometimes in the presence of an amorphous 1,4/1,2 polybutadiene block copolymer) led to a family of blends with attractive mechanical behavior.
