Abstract:
A silicone polymer having a three-dimensional crosslinked structure obtained by polymerizing:at least one of: an organohydrogen polysiloxane of the formula (A1): R1aR2bHcSiO(4âˆ’aâˆ’bâˆ’c)/2â€ƒâ€ƒ(A1) â€ƒand, an organohydrogen polysiloxane of the formula (A2): R1dHeSiO(4âˆ’dâˆ’e)/2â€ƒâ€ƒ(A2), â€ƒand; at least one of: a polyoxyalkylene of the formula (B1): CfH2fâˆ’1(CgH2gO)hCfH2fâˆ’1â€ƒâ€ƒ(B1) a polyoxyalkylene of the formula (B2): a polyoxyalkylene of the formula (B3): â€ƒand, an organopolyoxy alkylene (B4) of the formula (B4): R1jR5kSiO(4âˆ’jâˆ’k)/2â€ƒâ€ƒ(B4); â€ƒwhich silicone polymer is capable of containing or dissolving and swelling its same weight or more of pentane-3,3,3-trifluoropropyl pentamethylcyclopentasiloxane &Parenopenst;wherein, in the formulae: R1, which may be the same or different, is a hydrocarbon group having 1 to 20 carbon atoms, which does not contain an aliphatic unsaturated bond and which is optionally substituted or unsubstituted, provided that 11 to 60 mole % of the R1 groups are a fluorine-substituted monovalent hydrocarbon group, R2, which may be the same or different, is an organic group of the formula â€”CfH2fO(CgH2gO)hR6, R3, which may be the same or different, is a hydrogen atom or a monofunctional hydrocarbon group containing 1 to 10 carbon atoms which does not contain aliphatic unsaturated bonds and which is optionally substituted or unsubstituted, R4, which may be the same or different, is an organic group identical to R3 or is â€”CfH2fâˆ’1, R5 is a monofunctional hydrocarbon group having 2 to 10 carbon atoms containing a terminal vinyl group, and R6 is a hydrogen atom or a monofunctional hydrocarbon group or acetyl group not containing aliphatic unsaturated groups, which is optionally substituted or unsubstituted, a is about 1.0-2.3, b is about 0.001 to 1.0, c is about 0.001-1.0, d is about 1.0-2.3, e is about 0.001-1.0, j is about 1.0-2.3, and k is about 0.001-1.0, and about 1.5&lE;a+b+c&lE; about 2.6, about 1.5&lE;d+e&lE; about 2.6, about 1.5&lE;j+k&lE; about 2.6, f is an integer in the range 2-6, g is 2, 3 or 4, h is an integer in the range 1-200, i is an integer in the range 2-20, and x is 0 or 1&Parenclosest;.
