Chemically reactive fluorinated organosilicon compounds and their polymers

摘要

Chemically reactive fluorinated organosilicon compounds as described for use as, e.g., lubricants, sealants and elastomers, are described corresponding to the formulae X2R12Si I or XR22Si(R3SiR22)zX II where X a represents a reactive group selected from a halogen, hydroxyl, alkoxy, acetoxy, amino, alkyl amino or dialkyl amino, z is from 1 to 5, inclusive, at least one of the R1 radicals and at least one of the R2 radicals bonded to each of the silicon atoms are derived from: 1) a monovalent telomer of fluorinated olefins; 2) a monovalent cotelomer of (a) chlorotrifluoroethylene and a fluoropropene, (b) chlorotrifluoroethylene and vinylidene fluoride, (c) chlorotrifluoroethylene, a fluoropropene and a fluoroethylene, fluoride and a fluoropropene, (d) vinylidene, (e) a fluoroethylene and a perfluoroalkyl vinyl ether, (f) a fluoroethylene, chlorotrifluoroethylene and a perfluoroalkyl vinyl ether, (g) a fluoroethylene, a fluoropropene and vinylidene fluoride, (h) a fluoroethylene, chlorotrifluoroethylene and vinylidene fluoride, or (i) a fluoropropene, chlorotrifluoroethylene and vinylidene fluoride, wherein the telomers and cotelomers are bonded to silicon through a non-halogenated alkylene radical of 2,3,4 carbon atoms and the alkyl groups of the perfluoroalkyl vinyl ethers have from 1 to 3 carbon atoms; or 3) a monovalent oligomer of fluorinated oxetanes and oxiranes, where said oligomer is bonded to silicon by a non-halogenated ethylene or trimethylene radical; any remaining R1 and R2 radicals are an alkyl of 1 to 4 carbon atoms, alkenyl, perfluororalkyl-di-methylene, trimethylene or tetramethylene, phenyl or a perfluoroalkyl-substituted phenyl radicals, wherein the perfluoroalkyl portion of the perfluoroalkyl-substituted radicals has 1 to 4 carbon atoms; and R3 is derived from a divalent telomer or cotelomer from the same group of olefins and perfluoroalkyl vinyl ethers, a divalent oligomer derived from fluorinated oxetanes and fluorinated oxiranes, or is -[CH2CH2CH2OC(CF3)2]2Ph, wherein PH represents a meta-phenylene radical.
