  • Aliphatic polyesters of .epsilon.-caprolactone, p-dioxanone and gycolide
    Patent number: 5951997
    Abstract: Absorbable, segmented polymers of aliphatic polyesters based on lactone monomers glycolide, p-dioxanone and .epsilon.-caprolactone are described. The segmented polymers exhibit a broad range of properties, especially high strength, low modulus and fast in vivo absorption, useful in a variety of medical devices. The polymers of the present invention have such properties, making them useful in medical devices for plastic surgery indications.
    Type: Grant
    Filed: June 30, 1997
    Date of Patent: September 14, 1999
    Assignee: Ethicon, Inc.
    Inventors: Rao S. Bezwada, Kevin Cooper, Modesto Erneta
  • Aliphatic polyesters of trimethylene carbonate epsilon-caprolactone and glycolide
    Patent number: 5854383
    Abstract: Absorbable, segmented copolymers of aliphatic polyesters based on lactone monomers glycolide, trimethylene carbonate and .epsilon.-caprolactone are described. The segmented copolymers exhibit a broad range of properties, especially high strength, low modulus and fast in vivo absorption, useful in a variety of medical devices. The copolymers of the present invention have such properties, making them useful in medical devices for plastic surgery indications.

  • Process for producing absorbable segmented copolymers with a substantially uniform sequence distribution
    Patent number: 5844067
    Abstract: The present invention provides a process for producing absorbable segmented copolymers of aliphatic polyesters with a uniform sequence distribution comprising copolymerizing at least two aliphatic polyester monomers wherein one of the monomers will transesterify under copolymerization conditions to form a segmented block copolymer; then quenching the copolymerization by cooling the segmented block copolymer below the temperature at which transesterification will occur in less than 60 minutes.
    Type: Grant

  • Hydrochlorination of spray dried magnesium chloride
    Patent number: 4085198
    Abstract: Hydrous magnesium chloride in the form of spray dried particulate material of relatively high density is predried, initially using a dry gas at elevated temperature and for a period of time sufficient to partially hydrolyze the magnesium chloride and reduce the chemically combined water to at least as low as about 3.0%, and thereafter hydrochlorinated to reduce the oxides of Mg to at least as low as about 0.6% as MgO.
