ABSTRACT:
Highly water absorbent films and fibers are prepared by photopolymerizing an alkaline metal salt of acrylic acid, at least one alkyl acrylate or methacrylate wherein the alkyl group contains 10 to 30 carbon atoms, at least one alkyl acrylate or methacrylate wherein the alkyl group contains 1 to 4 carbon atoms and a photoinitiator. The resulting interpolymers are particularly useful in the preparation of highly absorbent personal hygiene and care products.
