Abstract

A method of preparing highly absorbent interpolymers from an alkaline metal salt of acrylic acid, at least one alkyl acrylate or methacrylate wherein the alkyl group contains 10 to 30 carbon atoms and at least one alkyl acrylate or methacrylate wherein the alkyl group contains 1 to 4 carbon atoms by subjecting the mixture of monomers to an electron beam source causing said monomers to polymerize substantially completely. The resulting interpolymers are particularly useful in the preparation of highly absorbent personal hygiene and care products.
