  • Electrophilic polyethylene oxides for the modification of polysaccharides, polypeptides (proteins) and surfaces
    Patent number: 5650234
    Abstract: Several poly(ethylene glycol) mixed carbonates and their preparation are closed. These carbonates are synthesized by conversion of polyethylene glycol first to the chloroformate then by reaction with the hydroxyl group of N-hydroxybenzotriazole or 2-hydroxypyrimidine or N-hydroxy-2-pyrrolidinone. These mixed carbonate analogs smoothly react with amino groups in aminoglycans and protein and amino containing surfaces to form stable, hydrolysis resistant carbamate linkages.

  • Hydrocyclosiloxane membrane prepared by plasma polymerization process
    Patent number: 5463010
    Abstract: Plasma polymerized membranes comprising polymerized aliphatic hydrocyclosiloxane monomers optionally copolymerized with co-monomers and methods for their preparation are described. These methods may be used to coat substrates to impart properties such as hydrophobicity, thromboresistance, gas permeability and biocompatibility.
