Estimating the term…
An interpolymer of at least one olefinically unsaturated carboxylic acid containing at least one activated carbon-to-carbon olefinic double bond and at least one carboxyl group, in an amount of more than 15% by weight based upon the weight of the interpolymer, and at least one steric stabilizer surfactant having at least one hydrophilic moiety and at least one hydrophobic moiety and a linear block or a random comb configuration, or mixtures thereof, made by polymerizing olefinically unsaturated carboxylic acid monomers in an organic media, in the presence of free a radical forming catalyst, and the steric stabilizer.
A method of making an interpolymer comprising interpolymerizing at least one olefinically unsaturated carboxylic acid or anhydride monomer containing at least one activated carbon to carbon olefinic double bond and at least one carboxyl group, and at least steric stabilizer having at least one hydrophilic moiety and at least one hydrophobic moiety and selected from the group consisting of:
