Associative Monomers and Polymers

摘要

The following are claimed: (a) polymer of a non-ionic urethane monomer comprises at least two repeating units of structure (I); (b) polymer of a non-ionic urethane monomer comprising at least two repeating units of structure (II); (c) copolymer comprising: (i) 30-99 mole.% monoethylenically unsatd. 3-8C monocarboxylic acid or ester monoethylenically unsatd. 4-8C dicarboxylic acid or ester and/or vinyl esters of satd. 1-8C monocarboxylic acid; and (ii) 0.1-70 mole.% of a non-ionic urethane monomer (III) forming repeat unit (I); (d) copolymer comprising (a)' part (i); (b) 0.1-35 mole.% of a non-ionic urethane monomer (IV) forming repeat unit (II), where R, R1, R2 = H, CH3, -CH2CH3. In (III) R2 = 1-4C linear or branched alkyl. R3 = 1-4C linear or branched alkyl. x,y = 1-50, where the sum of x+y is not greater than 100; A = 2-20C alkyl, aryl or alkaryl alkylene gp. n = at least 1. p,q.r = 1-50 where the sum of p+q+r is not greater than 150. Preferably, R is H, R1 is -CH3 and A is C6H5C(R1)(R2).
