Reaktionsschritte

A 0.3% solution of 0.2 g of poly(isobutylene-co-isoprene) was prepared in 99.7% of a 1:2 mixture of 2,2,4-trimethylpentane and CCl4. The solution was purged with N2, heated to 75 C., 0.09 g of azobisisobutyronitrile was added, followed by 5 g of methylmethacrylate, added over a period of one half hour. The polymerization was carried out for 8 hours with constant mechanical stirring, under a N2 atmosphere. After cooling the reaction mixture to room temperature, the cleaning procedure used was identical to that of Example 1.
