  • Process for cross-linking an acrylic polymer or copolymer or an acrylic derivative of a copolymer and the cross-linked acrylic polymer thereby obtained
    Publication number: 20040209997
    Abstract: A cross-linked acrylic polymer that is highly biocompatible is prepared from a water-soluble acrylamide monomer by preparing an aqueous polymerization solution containing an acrylamide monomer and a catalyzing agent; polymerizing the monomer present in the polymerization solution by agitating and heating the polymerization solution. The polymerization is conducted in the presence of gaseous oxygen.
