    摘要: A method for making flexible polyurethane foam in which a polyisocyanate is reacted with a polyol in the presence of a urethane catalyst, a blowing agent, optionally a silicone surfactant cell stabilizer, and a cell opening additive. The cell opening additive comprises an active methylene or methine compound which also contains a tertiary amine. Preferred cell opening additives are 2-cyano-N-[3-(dimethylamino)-propyl]acetamide and (NC)CH 2 C(O)OCH 2 CH 2 N(CH 3 )CH 2 CH 2 OCH 2 CH 2 N(CH 3 ) 2 .

    摘要: The present invention is directed to a rigid, lightweight filled resin foam having voids dispersed in a continuous phase which is formed from a polyester hybrid resin having reinforcing particles dispersed therein. The hybrid resin forms a complex cross-linked network (20) which may interact with other polymer networks in the continuous phase either by cross-linking or by forming an interpenetrating polymer network. The present invention is also directed to a process for preparing the above rigid, lightweight resin foam, and to a composition for use in this process. The foam of the present invention is useful in building materials and the like requiring high tensile and compressive strength and corrosion and thermal resistance.
