Abstract
A polymer mixture includes 10 to 90 wt. % of polymer 1 and 10 to 90 wt. % of polymer 2, the total being 100 wt. %. Polymer 1 is polymerized from (a1) 70-95 wt. % of C1-C12 alkylester of (meth)acrylic acid, and (b1) 5-30% wt. % of C2-C8 alkyl ester of (meth)acrylic acid with a quaternary cationic group in the alkyl group. Polymer 2 is polymerized from (a2) 70-95 wt. % of C1-C12 alkylester of (meth)acrylic acid, and (c2) 5-30 wt. % of C2-C6 hydroxy-alkylester of (meth)acrylic acid. Monomers (a1) and (b1) add up to 98-100 wt. %, and most preferred to 100 wt. %. Monomers (a2) and (c2) add up to 98-100 wt. %, most preferred to 100 wt %.
