Abstract:
1. A polymer composition comprising: a base polymer comprising polyethylenes, polyproplenes, poly(ethylene-co-propylene), polyamides, polyesters, polyurethanes, polyvinylchlorides, ethylene-propylene-diene monomer rubber, butadiene rubber, styrene-butadiene rubber, natural rubber, or a combination comprising at least one of the foregoing; an acrylic copolymer comprising an acidic monomer and an amide monomer present in a weight ratio of 95:5 to 5:95 wherein the acrylic copolymer is present in an amount of 30 to 200 parts by weight per hundred parts by weight of the base polymer; and a refined oil in which the acrylic copolymer is dispersed in the refined oil to form a liquid dispersed polymer, wherein the refined oil comprises a C wherein the polymer composition is swellable when treated with an aqueous medium, non-aqueous medium, or both.
