摘要：

A polymer blend of ductile polymer with brittle polymer, e. g. , polycarbonate (PC) with poly(styrene-co-acrylonitrile) (AS), is a new way to design toughened plastics. Both the stiffness and the toughness of ductile polymer can be improved by inclusion of the brittle polymer particles. In order to find out new combinations similar to PC/AS, the authors investigated mechanical properties of various blends consisting of ductile and brittle polymers. Morphological studies by SEM and TEM revealed the cold drawing mechanism of brittle polymer particles, by which the impact energy is absorbed to improve the toughness. Analysis of stress concentration on the dispersed particles was undertaken by using the modified Eshelby theory.
