A diorganopolysiloxane in which a polymerizable functional group is present at one (or both) molecule chain ends and in which an arbitrary group is present at the other end can be easily synthesized. The synthesis involves the opening of a cyclotrisiloxane using an alkali metal silanolate which bears the polymerizable functional group, followed by a capping reaction. The resulting diorganopolysiloxane can be used effectively as a feed material for manufacturing silicone rubbers, feed material for manufacturing novel grafted organopolysiloxanes, comonomer components for resins other than organopolysiloxanes or plastics, etc.
可以轻松合成一种具有可聚合官能团的二有机聚硅氧烷,其中该官能团存在于一条(或两条)分子链的末端,并且在另一端存在任意基团。该合成方法涉及使用带有可聚合官能团的碱金属硅醇酸盐打开环三硅氧烷,然后进行封顶反应。得到的二有机聚硅氧烷可有效地用作制造硅橡胶的原料、制造新型接枝有机聚硅氧烷的原料、非有机聚硅氧烷或塑料的共聚单体组分等。
