  • Patent number: 9410014
    Abstract: Embodiments relate to a relatively rapid transesterification process including transesterifying condensation polymers such as polyethylene terephthalate (PET), or other polyesters used in commerce, with a modifying monomer mix containing other monomers to manufacture new polymers containing the pre-condensed moieties. The process preferably only involves transesterification as a reaction mechanism. The process preferably produces a rapid buildup of molecular weight and/or polymer uniformity by the high temperature transesterification of the condensation polymer with the modifying monomer mixture. The process can be performed in any suitable vessel including an extrusion line, and it has the advantage of greatly reduced cycle times over currently used condensation polymer utilization processes such as the recycling of PET into other materials.

  • Patent number: 9289540
    Abstract: A modified medical device substrate surface designed to improve adhesion of biomimetic surfactants to the medical device surface, thus reducing the risk of thrombosis is described. The surface modification is accomplished through either an application of a tie layer of a hydrophobic material on the substrate surface intermediate the biomimetic coating or through incorporation of a hydrophobic dopant in the polymeric substrate prior to extrusion or molding. Either method creates a hydrophobically modified surface that enhances the biomimetic surfactant bonding strength.

  • Patent number: 9200112
    Abstract: The present invention relates to a composition comprising a semi-crystalline, absorbable copolymer formulation wherein the first component is hydroxy-capped polycondensation product of diglycolic acid and a mixture of two idols, diethylene glycol (DEG) and ethylene glycol (EG), with DEG added in larger molar amount, and wherein the second component, glycolide is incorporated during the subsequent ring-opening polymerization. The resulting hydrophilic resin has low crystallinity level, glass transition temperature, Tg, slightly below room temperature, and may be particularly useful for making monofilaments, multifilaments, microspheres, or melt blown nonwoven constructs or other medical devices where fast hydrolysis rates and superior mechanical properties are desirable.
