    • Tertiary amine catalysts having isocyanate reactive groups that are capable of forming thermally stable covalent bonds able to withstand temperatures up to 120C. These catalyst can be used to produce polyurethane foam having the following desirable characteristics: a) very low chemical emissions over a wide range of environmental conditions and isocyanate indexes (e.g. indexes as low as 65 but higher than 60) while meeting all physical property requirements; b) sufficient hydrolytic stability to maintain the catalyst covalently bound to foam without leaching of tertiary amine catalyst when foam is exposed to water or aqueous solutions even at temperatures higher than ambient (temperature range 25C to 90C); and c) stable contact interface between the polyurethane polymer and other polymers (for example polycarbonate) with minimal migration of tertiary amine catalyst from polyurethane polymer to other polymers yielding no noticeable polymer deterioration at the point of contact even under conditions of heat and humidity.
    • 具有异氰酸酯反应性基团的叔胺催化剂能够形成能够承受温度高达120℃的热稳定共价键。 这些催化剂可用于生产具有以下所需特性的聚氨酯泡沫:a)在满足所有物理性能要求的同时,在广泛的环境条件和异氰酸酯指数(例如低至65但高于60的指数)下,化学物质排放量非常低。 b)即使在高于环境温度(温度范围25℃至90℃)的情况下,泡沫暴露于水或水溶液时,b)足够的水解稳定性以保持催化剂共价结合于泡沫体而不浸提叔胺催化剂; 和c)聚氨酯聚合物和其它聚合物(例如聚碳酸酯)之间的稳定的接触界面,其中叔胺催化剂从聚氨酯聚合物到其它聚合物的最小迁移,即使在热和湿度的条件下也在接触点处没有显着的聚合物劣化。
