Novel Methods for Changing Domain Size and Shape of Poly(butyl acrylate-co-acrylic acid) in Poly(styrene-co-acrylonitrile) Matrix

摘要

Domain size and shape are very important characteristics for rubber toughened polymeric materials,such as HIPS (High-Impact Polystyrene),ABS (Acrylonitrile/Butadiene/Styrene),ASA (Acrylonitrile /Styrene/Acrylate). It has been well known that it is possible to make various domain size and shape of rubber phase according to composition,viscosity ratio of rubber phase and matrix,shear,interfacial tension,etc.1-5 Besides those conventional methods for controlling domain size and shape of rubber phase,we report novel methods for changing domain size and shape,which are based on the reaction between carboxylated poly(butyl acrylate) and di-ol during matrix formation.
