PURPOSE:To improve the sensitivity to Cl ion and resistance to org. staining by forming a specific linear polymer into a film and crosslinking the film. CONSTITUTION:A compsn. obtd. by compounding a linear polymer comprising 10-90mol% units of formula I and 90-10mol% units of formula VI (wherein R<4> is H or 5C or lower alkyl) with 10-200wt.% 10C or higher liner alcohol is formed into a 0.1mum to 5mm thick film, which is thermally crosslinked at 30 deg.C or higher. In formula I, Y is H, alkyl, or cyano; X<-> is a halogen ion or a group of atom forming an anion; Z is a group of formula II to V; n is 1-10; R<1> and R<2> are each 5C or lower alkyl, halogenated alkyl, hydroxyakyl, or benzyl; A is a monovalent nonionic group having two or three long-chain hydrophobic groups or one long-chain hydrophobic group contg. a rigid segment in the chain; B<1> and B<2> are each a monovalent nonionic long-chain hydrophobic group; R<3> is -(CH2)m-, -CH2(CH2OCH2)mCH2-, etc.; and m is n. |
