Abstract:
A polymer of olefinically unsaturated monomers consisting of:(a) olefinically unsaturated monomer which contains at least one secondary amino group; and(b) olefinically unsaturated monomer which contains neither amino nor hydroxyl groups and which consists of a mixture of at least one ester of acrylic or methacrylic acid containing from 1 to 18 carbon atoms in the alcohol radical and at least one member selected from the group consisting of styrene and alkyl substituted styrene;wherein:(c) the olefinically unsaturated monomer which contains at least one secondary amino group constitutes from 10 to 50 percent by weight, based on the total weight of the monomers used;(d) the olefinically unsaturated monomer which contains neither amino nor hydroxyl groups constitutes from 50 to 90 percent by weight, based on the total weight of the monomers used;(e) the amine content of the polymer is in the range of from 0.05 to 2.70 milliequivalents per gram; and(f) the number average molecular weight of the polymer is in the range of from 500 to 50,000.
