Abstract
A study of the graft polymerization of styrene and methyl methacrylate using preozonized polyvinyl chloride (PVC) as an initiator has been made. During the ozonization at room temperature, the weight of PVC increased with the time and peroxidic group was formed. Infrared spectra of the preozonized PVC showed the absorption bands of carbonyl and ozonide groups. These preozonized PVC could initiate the polymerization of styrene and methyl methacrylate to yield the graft copolymer. The efficiency of grafting was as low as 5-1O% and a large amount of homopolymer was obtained.
