摘要

1. The monomer of formula (I) R- (AO) - (BO) -R ', where m and n are integers less than 150, at least one of which is not zero, - A and B denote alkyl groups that differ from each other and containing from 2 to 4 carbon atoms, wherein the AO group is preferably ethylene oxide and the BO group is preferably propylene oxide, - R is a polymerizable unsaturated group, preferably methacrylate, - R 'is characterized in that it consists of at least one group formula (II): CH- (CH) -CH (CH) CH- (CH) -, where p and q are integers, at least one of which is non-zero, where 5 p + q 13, r is an integer equal to 0.2. The monomer according to claim 1, characterized in that n = 0, AO is ethylene oxide and m is from 20 to 40.3. A HASE-type polymer consisting of: a) (meth) acrylic acid, b) at least one (meth) acrylic acid ester, c) at least one monomer of the above formula (I) R- (AO) - (BO) -R ', where m and n are integers less than 150, at least one of which is not zero, - A and B denote alkyl groups that are different from each other and contain from 2 to 4 carbon atoms, while the group AO preferably denotes ethylene oxide and the group BO preferably denotes propylene oxide, - R denotes a polymerizable unsaturated group, pre respectfully methacrylate, R 'is characterized in that it consists of at least one group of formula (II) CH- (CH) -CH (CH) CH- (CH) -, where p and q are integers of at least one of which is not equal to zero, where 5 p + q 13, r is an integer equal to 0.4. The polymer according to claim 3, characterized in that it consists of each of its monomers, expressed, wt.%: A) from 20% to 50%, preferably from 35% to 45%, (meth) acrylic acid�
