| 摘 要： | 由1,3，5-三甲基三氟丙基环三硅氧烷的阴离子本体开环缩聚合成了氟硅生胶，并对生胶进行过氧化物交联。发现聚合过程存在氟硅聚合物和小分子环状物的平衡，控制聚合时间在40～60min,得到了高转化率和高分子量氟硅生胶，引入乙烯基共聚单体对分子量影响不显著，随着生胶中乙烯基含量增加，过氧化物交联氟硅胶的交联程度增加。

| Abstract: | Poly(methyl(trifluoropropyl) siloxane)(PMTFPS) was prepared by bulk ring-opening polymerization of 1,3,5-trimethyl-trifluoropropyl cyclotrisiloxane,and crosslinked by peroxide compound.It was found that PMTFPS with high conversion and high molecular weight could be obtained by controlling the polymerization time.The introduction of vinyl groups-containing commoner had no significant effect on molecular weight,while the crosslinking density of peroxide-crosslinked PMTFPS increased with the increase of vinyl groups content. |
