摘要
以四甲基氢氧化铵为催化剂，用蒸汽压法研究了八甲基环四硅氧烷的聚合动力学，获得了７７～１１０℃间的聚合速率常数，并计算出反应活化能为１０３０ｋＪ／ｍｏｌ。
Taking tetramethylamnionium as catalyst,the polymerization kinetics of octamethylcyclotetrasiloxane was studied by means of vapor pressure method.The rate of polymerization at 77～110 ℃ was obtained and activation energy was calculated out to be 103 0 kJ/mol.
