Abstract

Statistical copolymers of styrene and acrylonitrile, covering a wide range of compositions, were synthetized by emulsion polymerization conducted to both low and high conversion. The weight‐average molecular weights of the copolymers were determined by light scattering and correlated with intrinsic viscosities measured in methyl ethyl ketone and/or dimethyl formamide solutions. The copolymers polymerized in emulsion are suggested to consist of macromolecules with long chain branching.

Styrene ab initio emulsion polymerizations were conducted at 70ЊC in an automated reaction calorimeter. Two polymerizations were performed, one above and the other below the critical micelle concentration (CMC) of the surfactant, thus ensuring differing polymerization kinetics between the two: the s
