    摘要: Block copolymers are formulated with multifunctional chain extenders. The block copolymers include a soft segment and a hard segment made from a diisocyanate, an alkylene diamine chain extender, and a multifunctional chain extender which provides delayed crosslinking. The multifunctional chain extenders have a functionality ≥3 and typically have at least one OH group. The multifunctional chain extenders may be aliphatic or aromatic triols or polyols, or may have other configurations, as described. The resulting block copolymers have improved mechanical properties such as compression set. They may be used in medical applications, or in industrial applications such as seal and gasket applications, including O-rings, window seals, and automotive gaskets. The initially-formed polyurethane resin behaves as a thermoplastic processable material, while the configured end-use product is thermoset.

    摘要: A silicone-containing composition comprises the reaction product of a first component and an excess of an isocyanate component relative to the first component to form an isocyanated intermediary. The first component is selected from one of a polysiloxane and a silicone resin. The first component includes a carbon-bonded functional group selected from one of a hydroxyl group and an amine group. The isocyanate component is reactive with the carbon-bonded functional group of the first component. The isocyanated intermediary includes a plurality of isocyanate functional groups. The silicone-containing composition comprises the further reaction product of a second component, which is selected from the other of the polysiloxane and the silicone resin. The second component includes a plurality of carbon-bonded functional groups reactive with the isocyanate functional groups of the isocyanated intermediary for preparing the silicone-containing composition.

    摘要: A polyurethane material is provided that reduces or eliminates the need for use of polycarbonates and improves biostability of the polyurethane material while maintaining preferred physical properties. This polyurethane material is comprised of a hard block segment, such as methylene diphenyl diisocyanate (MDI), a phenol-based silicone soft segment and preferably includes a chain extender, such as butanediol. This polyurethane material is particularly useful for medical implantation applications, especially with respect to coatings for lead and assemblies.
