    摘要: Water blown, thermosetting unsaturated polyester-polyurethane hybrid foam compositions are formed by the reaction of an A side composition and a B side composition. The A side composition comprises a polyfunctional isocyanate compound and a free radical initiator. The B side composition comprises a mixture of: (i) an ethylenically unsaturated monomer solution having dissolved therein about 30-90 weight percent of a polyester polyol having at least one ethylenically unsaturated group per molecule which has predominantly hydroxyl end groups; (ii) an amine compound having two or more primary or secondary amine groups in an amount effective to react with the A side composition to form small urea domains finely dispersed within a continuous polyester-polyurethane hybrid phase; and (iii) about 25 to about 150 equivalents water based on 100 equivalents of active hydrogen in the B side. When the A and B side compositions are reacted, the composition will have a ratio of active NCO groups of the isocyanate to active NH groups of the amine compound of between about 10:1 and about 50:1. and an isocyanate index, NCO:(NH+OH+COOH+HOH), of between about 0.5 and about 2.0.

    摘要: Improved polyphthalamide compositions, particularly for injection molding applications, comprise a polyphthalamide component with at least two recurring units selected from terephthalamide, isophthalamide and adipamide units and having high heat deflection temperature when filled with glass fibers; reinforcing fibers; and effective amounts of particulate talc. Molded articles prepared from such compositions exhibit excellent mechanical and thermal properties, including high heat deflection temperature, even when molded using molds heated below Tg of the polyphthalamide component, often facilitating molding using steam or hot water-heated molds.
