本文报导了几种新的极性基取代环四硅氧烷化合物——[邻羧苯(基)硫基]甲基七甲基环四硅氧烷、(羧甲基硫基)甲基七甲基环四硅氧烷、(1,2,3——三甲酸乙酯基异丙氧基)甲基七甲基环四硅氧烷的合成及其开环聚合作用。这些化合物的结构为下式所代表:式中, 我们采用了对甲苯磺酸,浓硫酸——高锰酸钾,浓硫酸分别作为开环聚合催化剂,对上述极性基取代环四硅氧烷化合物的聚合作了比较。
In this paper, several new polar group substituted cyclotetrasiloxane compounds, such as [(ortho-carboxyphenyl) thio] methylheptamethylcyclotetrasiloxane, (carboxymethylthio) Synthesis and ring opening polymerization of methylcyclotetrasiloxane, (1,2,3 - trimethoxyisopropoxy) methylheptamethylcyclotetrasiloxane. The structures of these compounds are represented by the following formula: wherein, we use p-toluenesulfonic acid, concentrated sulfuric acid - potassium permanganate, concentrated sulfuric acid as a ring-opening polymerization catalyst, respectively, the polar group substituted cyclotetrasiloxane The polymerization of compounds was compared.
