Abstract

The regulating action of aliphatic mercaptans in free radical polymerization has been known for a comparatively long time. The reaction rate constants for chain transfer for some mercaptans were found as well as the conditions for their effective use when obtaining different polymer composites, including high impact polystyrene (HIPS). However, introduction of transfer-agents (regulators) into polymerization systems affects not just the molecular weight characteristics of the polymer. In addition to lowering the MW of homopolystyrene which is formed during styrene polymerization with polybutadiene, mercaptans change the conditions of rubber phase dispersion and thereby affect the HIPS morphology.
