  • Process for the preparation of a polymeric hydrogel based on a highly purified polyvinylalcohol and uses thereof
    Publication number: 20090053313
    Abstract: The present invention relates to the preparation of a completely biocompatible and injectable, crosslinked polymeric hydrogel based on a polyvinyl alcohol. Said polymer, which is produced in a highly purified form, proved particularly suitable for the preparation of a filler to be employed in medicine and cosmetics, for the purpose of filling, correcting or treating deficits of different kind, origin and size of the soft tissues.

  • 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.
