Abstract:
1. A copolymer comprising, per 100 mol %: a) more than 70 mol % and up to 99.8 mol % of hydrophobic monomer units (A) derived from stearyl methacrylate; b) from 0.1 mol % to 30 mol % of monomer units (B) derived from at least one monomer of a compound of formula (I): c) from 0.1 mol % to 30 mol % of monomer units (C) derived from at least one neutral monomer selected from the group consisting of acrylamide, methacrylamide, N,N-dimethylacrylamide, N,N-diethylacrylamide, N-isopropylacrylamide, 2-hydroxyethyl acrylate, 2,3-dihydroxypropyl acrylate, 2-hydroxyethyl methacrylate, 2,3-dihydroxypropyl methacrylate and N-vinylpyrrolidone, wherein the sum of mol % for each monomer units (A), (B) and (C) do not exceed said 100 mol %.
