A crosslinking system consisting of 1,1-di-t-butylperoxy-3,3,5-trimethyl cyclohexane peroxide and trimethylolpropane trimethacrylate (TMPTMA) has been used to introduce crosslinks into unplasticized poly(vinyl chloride) (PVC). The influence of the concentration of both reagents has been investigated

Abstract
Suspension polymerization of vinyl chloride was studied using five organic peroxides which show similar polyerization rates. Initial coloring of polymers obtained depended on the kinds of peroxides and the amount of peroxides used. Initial coloring of PVC had no relation to water solubility of the peroxides, but depended greatly on their susceptibility to hydroysis. Organic peroxides with susceptibility to hydrolysis remained low in the polymer, and yielded PVC showing preferable initial coloring.

## Abstract The optimum conditions for crosslinking rigid poly(vinyl chloride) with trimethylolpropane trimethacrylate (TMPTMA) and peroxide have been examined. The extent of crosslinking was measured by determining gel content by Soxhlet extraction in tetrahydrofuran. Mechanical properties were me
