Abstract

The eff ect of butadiene rubber molecular parameters on conversion dependencies and viscosity characteristics of the process of graft copolymerization of styrene, microstructure and quality indicators of the synthesized samples of impact-resistant polystyrene was studied. It is testifi ed that an increase in the molecular mass of the elastomer does not aff ect the monomer conversion, however, it leads to a phase inversion shifting to the region of lower conversion degrees of styrene. In this case, an increase in the size of rubber particles and an increase in the content of the gel fraction are observed in the copolymer. The established changes in the microstructure correlate with the properties of high-impact polystyrene.
