Versuchsvorschrift

Copolymerization was carried out in the same manner as Example 7 by varying the feed ratio of p-trimethylsilylstyrene to styrene. The composition of the copolymer thus obtained was calculated in 13C-NMR analysis from the ratio of peak area at around 145 ppm to that at around 146 ppm. The results are given in Table 2. Also as a result of 13C-NMR analysis, a sharp peak assignable to quaternary carbons of aromatic ring was observed at around 146 ppm, demonstrating the syndiotactic configuration.
