  • Coated webs
    Patent number: 5350627
    Abstract: Biodegradable polymers may be used as binders for impregnating or coating fibrous webs. The resulting web is degradable and also the fibers within the web may be more easily recycled.
    Type: Grant
    Filed: June 11, 1993
    Date of Patent: September 27, 1994
    Assignee: Camelot Technologies, Inc.
    Inventors: Speros P. Nemphos, Gregory B. Kharas
  • Higher heat degradable polymer alloys
    Patent number: 5300576
    Abstract: The thermal properties, such as heat distortion temperature of biodegradable polymers, such as polylactic acid, polyglycolides, polybutyric acid and copolymers of butyric and valeric acid, may be increased by blending them with a polymer having Tg from 75.degree. C. to 200.degree. C. and a Hildebrand parameter (.sigma.) of not more than 3 MPA.sup.1/2 different from the biopolymer.
    Type: Grant
    Filed: October 3, 1991
    Date of Patent: April 5, 1994
    Assignee: Camelot Technologies, Inc.
    Inventors: Speros P. Nemphos, Gregory B. Kharas
  • Continuous lactide polymerization
    Patent number: 5136017
    Abstract: Lactide monomers and copolymers may be polymerized by a continuous process using one or more continuous stirred tank reactors. The process offers productivity and product quality advantages over the batch process of polymerization.
