CURABLE MOLDING COMPOSITION AND ITS USE FOR PRODUCING THERMOSET FIBER-REINFORCED MOLDED ARTICLES |
摘要 |
<p>Curable molding compositions comprising a mixture of: I. from about 25 to about 90 weight percent of a thermosetting resin containing: (a) from about 5 to about 95 weight percent of a polyester resin derived from the reaction of a poly(acrylate) and a vinyl monomer, said poly(acrylate) and vinyl monomer essentially free from functional groups reactive with the polyol of the polyisocyanate of (b); (b) from about 95 to about 5 weight percent of a polyurethane derived from the reaction of a saturated polyol and a polyisocyanate, said polyol and polyisocyanate free from unsaturated groups capable of copolymerizing with the poly(acrylate) or vinyl monomer of (a); and II. from about 75 to about 10 weight percent of one or more fibers with a melting point or a glass transition temperature above about 130 DEG C; wherein (b) constitutes less than 40 weight percent of (I) and (II). These compositions are especially suited to produce thermoset fiber-reinforced molded articles by rapid injection molding techniques.</p> |
