1. A copolymer composition comprising the reaction product of a reaction of:
(I) a cured polyorganosiloxane intermediate having repeating Si—O—Si units and at least one Si—OH functional group and having a surface having a water contact angle of less than or equal to 90° as determined by ASTM 5946-04; and (II) a polyfluoropolyether silane according to the general formula (A″):
Y—Za—[(OC3F6)b—(OCF(CF3)CF2)c—(OCF2CF(CF3))d—(OC2F4)e—(CF(CF3))f—(OCF2)g]—(CH2)h—X′—(CnH2n)—((SiR12—O)m—SiR12)i—(CjH2j)—Si—(X″)3-z(R2)z; wherein Z is independently selected from —(CF2)—, —(CF(CF3)CF2O)—, —(CF2CF(CF3)O)—, —(CF(CF3)O)—, —(CF(CF3)CF2)—, —(CF2CF(CF3))—, and —(CF(CF3))—; a is an integer from 1 to 200; b, c, d, e, f, and g are integers each independently selected from 0 to 200; h, n and j are integers each independently selected from 0 to 20; i and m are integers each independently selected from 0 to 5; X′ is a bivalent organic group or O; R1 is an independently selected C1-C22 hydrocarbyl group; z is an integer independently selected from 0 to 2; X″ is an independently selected hydrolysable group; R2 is an independently selected C1-C22 hydrocarbyl group which is free of aliphatic unsaturation; and Y is selected from H, F, and (R2)z(X″)3-zSi—(CjH2j)—((SiR12—O)m—SiR12)i—(CnH2n)—X′—(CH2)h—; wherein X″, X′, z, R1, R2, j, m, i, n and h are as defined above; provided that when subscript i is 0, subscript j is also 0; when subscript i is an integer selected from 1 to 5, subscript j is an integer selected from 1 to 20 and m is an integer selected from 1 to 5. |
