The Effects of Reaction Variables on the Grafting of Polystyrene ontoGround Tire Rubber

The surface of the ground tire rubber (GTR) was graft-modified with styrene (St) by solutionpolymerization. The effects of initiator content and temperature on the monomer conversion (X),grafting efficiency (GE), and grafting yield (GY) were investigated. The results showed that X, GE,and GY were increased with increasing temperature. The monomer conversion was highest when theinitiator to monomer molar ratio was nearly ۲.۴, while GE and GY were minimum at this initiatorcontent.
