CATIONIC GRAFT COPOLYMERIZATION OF STYRENE ONTO CHLORINATED BUTYL RUBBER

Abstract

Polymerization of styrene was carried out in cyclohexane solution of chlorinated butyl rubber with stannic chloride in a sealed tube, and the rate of polymerization of styrene was discussed. It was determined in terms of an increase in the weight of solid.
It was found that the rate was in proportion to the concentrations of styrene, chlorinated butyl rubber and stannic chloride, respectively.
