SILICON-CONTAINING ORGANIC FLUOROPOLYMERS AND USE OF THE SAME

摘要

Novel silicon-containing organic fluoropolymers which are appliable to materials over a wide range and which have excellent antifouling property. The silicon-containing organic fluoropolymer of the invention is represented by the general formula and has a number average molecular weight of from 5x10<2> to 1x10<5>: wherein Rf represents perfluoroalkyl; Z represents fluoro or trifluoromethyl; a, b, c, d and e each independently represent 0 or an integer of 1 or above, provided that a + b + c + d + e is not less than 1 and the order of the repeating units parenthesized by subscripts a, b, c, d and e occurring in the formula is not limited to that shown; Y represents hydrogen or alkyl containing 1 to 4 carbon atoms; X represents hydrogen, bromo or iodo; R<1> represents hydroxy or a hydrolyzable substituent group; R<2> represents hydrogen or a monovalent hydrocarbon group; l represents 0, 1 or 2; m represents 1, 2 or 3; and n represents an integer of 2 or above.
