摘　　要：1,3,5-三甲基-1,3,5-三(3′,3′,3′-三氟丙基)环三硅氧烷(F3)的阴离子开环聚合可以合成优越耐油耐溶剂性能的聚甲基三氟丙基硅氧烷(PMTFPS),但在开环聚合过程中“反咬”与再分布副反应严重,要得到高分子量、高产率的氟硅聚合物材料,必须严格控制聚合反应条件。文中总结了本体、溶液、细乳液中F3的阴离子开环聚合影响因素、机理与动力学,以及F3与其它单体共聚合反应等方面的研究进展。Poly[methyl(trifluoropropyl)siloxane] (PMTFPS) which exhibits superior fuel-and solvent-resistance may be obtained by the anionic ring-opening polymerization(ROP) of F_3, but the backbiting' and redistribution side reactions occurs during the polymerization. To produce high molecular weight and high yield fluorosiloxane polymeric materials, careful control of the polymerization conditions is essential. The factors, mechanism, kinetics of the anionic ROP of F_3 in bulk, in solution or in miniemulsion, and the progress in copolymerization of F_3 with other vinyl monomers were summarized in this paper.
