    摘要: The present invention provides a molded product composed of a polymer alloy of a polyamide polymer and at least one polyurethane polymer, polyurea polymer, and/or polyisocyanurate polymer. The polymer alloy is an interpenetrated network of different polymers, a semi-interpenetrating network of different polymers, or a polyblend of different polymers.Reactant streams containing the compounds for forming the polymers of the polymer alloy are admixed to form a reaction mixture. The liquid reaction mixture is preferably a substantially homogeneous mixture of the reactant compounds. Each reactant stream thus contains only a portion of the components required to obtain the polymer alloy product. The resulting mixture is then rapidly introduced into a mold wherein chemical reaction takes place and the polymer alloy forms. Preferably, the mold is heated. The solid polymer alloy product is then recovered from the mold.
