Terpolymerization studies. I. Terpolymerization of acrylonitrile, styrene, and esters of α‐cyanocinnamic acid

摘要

AbstractThe terpolymerizations of acrylonitrile, styrene, and seven esters of α‐cyanocinamic acid were investigated up to low conversions. Polymerizations, carried out in bulk at 70°C, were initiated by free radicals. The relationships between monomer feed and terpolymer composition were determined on a triangular coordinate graph as proposed by Slocombe. In all cases, there exists an azeotropic line, connecting the binary azeotrope of the pair acrylonitrile‐styrene and that of the various pairs of styrene with the esters of α‐cyanocinnamic acid, yet no real ternary azeotrope w
