Polymers are made by polymerization of an ionic monomer such as methacrylic acid or dialkylaminoalkyl (meth)-acrylate or -acrylamide and/or a substantially non-ionic monomer, optionally a cross linking agent, and an allyl ether of the formula CH.sub.2 .dbd.CR'CH.sub.2 OA.sub.m B.sub.n A.sub.p R where R' is hydrogen or methyl, A is propyleneoxy or butyleneoxy, B is ethyleneoxy, n is zero or an integer, m and p are zero or an integer less than n, and R is a hydrophobic group of at least 8 carbon atoms. The polymers are preferably made by oil in water emulsion polymerization. They can be used as thickeners particularly in environments containing surfactant and/or electrolyte, including especially emulsion paints, print pastes, alkaline liquors and acidic liquors.
