High performance polymer blends I: The impact behaviour of blends of polyvinylchloride and acrylonitrile-butadiene-styrene terpolymers as a function of the composition of the (Styrene-Acrylonitrile) copolymer-butadiene rubber-polyvinylchloride system

Blends of polyvinylchloride with acrylonitrile-butadiene-styrene graft terpolymers were studied as a ternary blend system of styrene-acrylonitrile copolymer, butadiene rubber and polyvinylchloride. The constituents and the compounding conditions were held constant and the blending ratios were systematically varied to cover an extensive ternary composition range. The impact fracture behaviours of these materials were studied by Izod impact tests. Various phenomenological aspects of the force-deflection response are discussed in relation to the blend composition and structure.
