Reaktionsschritte

In this example, a 1/11/88 PES/styrene/1,3-butadiene terpolymer was prepared using the procedure described in Example 34 except that the ratio of PES to styrene and to 1,3-butadiene was changed to 1:11:80 and the molar ratio of TMEDA to n-BuLi was also changed to 1:1. GC analysis of residual monomer with respect to polymerization time indicated that PES was randomly distributed along the polymer chain. The resulting terpolymer had a Tg at −42° C. and was determined to a have a ML-4 of 47.
