| 摘要: |
| 本文研究了用二甲基二氯硅烷和二苯基二氯硅烷的混合物与金属钠反应，制取可溶性的二甲基硅二苯基硅共聚物。结果表明：共聚物产率随两单体配比的接近而增大，分子量随二苯基二氯硅烷含量的增大而减小；单体配比相近时，反应时间基本上不影响共聚物的分子量及组成含量，但在反应初期共聚物产率随时间而增加；反应温度对共聚物产率、分子量基本上无影响；共聚物呈无定型非晶态结构。 |

| Abstract: |
| Soluble dimethylsilane-diphenylsilane copolymer has been prepared by the reaction of a mixture of dimethyldichlorosilane and diphenyldichlorosilane with metallic sodium. The results show that the yield of copolymer increases when the ratio of these two monomers approaches unity，the molecular-weight decreases with the increasing of diphenyldichlorosilane content. The molecular-weight and composition of the copolymer are basically unrelated to the reaction time，but the yield increases with time at the beginning. Reaction temperature basically has no influence on the yield and molecular-weight of the copolymer. It also shows that the copolymer is amorphous. |
