Abstract

A copolymer derived from a monomer mixture that includes monomers having the formulas: (A) and (B) wherein: Q is O or N; R10 is H or CH3; R11 is an organic group comprising a hydrolyzable silyl group; R12 is H or CH3; P is: (I); R1 is selected from H, an alkyl group, an aryl group, and a combination thereof; R2 is selected from an alkyl group, an aryl group, a combination thereof, and a Rf—Y—(CH2)x— group; Rf is a perfluorinated alkyl group; Y is selected from a bond, —S(O)2—N(CH3)—, —S(O)2—N(CH2CH3)—, —S(O)2—O—, —S(O)2—, —C(O)—, —C(O)—S—, —C(O)—O—, —C(O)—NH—, —C(O)—N(CH3)—, —C(O)—N(CH2CH3)—, —(CH2CH2O)y—, —O—, and —O—C(O)—CH═CH—C(O)—O—; n is an integer of greater than 2; x is an integer of at least 2; and y is an integer of at least 1.
