Terpolymerization studies. IV, Terpolymerization of ethyl acrylate, ethyl α-cyanocinnamate, and styrene

Ethyl acrylate, ethyl α-cyanocinnamate, and styrene were terpolymerized by free radical initiation at 60°C up to low conversion. The relationships between monomer feed and compositions of the terpolymers were determined by a triangular graph according to Slocombe. The terpolymers were characterized by their IR and Proton NMR spectra, intrinsic viscosity, and thermal behaviour. For a selected terpolymer, its adhesive properties for a number of substrates was investigated.
