PROCESS FOR PREPARATION OF FLUOROSILICON POLYMER |
摘要 |
Fluorosilicon polymers are disclosed that are prepared by a process comprising reacting a) iodinated oligomers having copolymerized units of perfluoro(methyl vinyl ether) and vinylidene fluoride or tetrafluoroethylene that contain 40-90 mole percent copolymerized units of vinylidene fluoride or tetrafluoroethylene and 10-60 mole percent copolymerized units of perfluoro(methyl vinyl ether), said oligomers having two functional endgroups and having a number average molecular weight between 1000 and 25,000 with b) a methoxyvinyl silane or an ethoxyvinyl silane to form a silicon-containing polymeric adduct that is further reacted with an acid to form a crosslinked fluorinated polymer. |
