报告了聚（甲基苯基亚甲硅烷基）1、聚（1，1，2-三甲基-2-苯基二亚甲硅烷基）2、聚（二甲基亚甲硅烷基-co-苯基甲基亚甲硅烷基）的两个样品3a和3b以及聚（苯基甲基亚甲硅烷基-co-n-己基甲基亚甲硅烷基）4的29 Si-NMR光谱。3a、3b和4的光谱表明，这些聚合物含有具有相当大的RMeSi和PhMeSi基团分离的嵌段区域。2的光谱显示没有立体定向聚合的证据。还描述了从1，1，2-三甲基-2-苯基二氯硅烷制备2。
The 29Si-NMR spectra are reported for poly(methylphenylsilylene), 1, poly(1,1,2-trimethyl-2-phenyldisilene) 2, two samples of poly(dimethylsilylene-co-phenylmethylsilylene), 3a and 3b, and poly(phenylmethylsilylene-co-n-hexylmethylsilylene), 4. The spectra of 3a, 3b, and 4 indicate that these polymers contain blocklike regions with considerable segregation of RMeSi and PhMeSi groups. The spectrum of 2 shows no evidence for stereospecific polymerization. The preparation of 2 from 1,1,2-trimethyl-2-phenyldichlorosilane is also described.
