摘要： A chain extending agent for reaction injection molding (RIM) comprising a normally liquid blend of butanediol and a toluene diamine mono-substituted with an electron withdrawing group and having the formula ##STR1## wherein X is vicinal to an amino radical and is selected from the group of halogen, CN, NO.sub.2, acyl, carboxylate and isomeric mixtures thereof, and wherein the butanediol and diamine are combined in a critical mole ratio of from 4:1 to about 19:1. The above blend is particularly useful in the preparation of large moldings of polyurethane-polyurea elastomer by the RIM or RRIM (reinforced reaction injection molding) process wherein instant preformed blend is added to a mixture of polyol reactant and catalyst before polymerization in the mold with isocyanate to produce a urethane/urea polymer product of improved properties. Accordingly, the invention also concerns an enhanced RIM or RRIM process and improved product by the use of a mixture of the present chain extender blend and polyol reactant maintainable in the liquid state at ambient temperature.
摘要翻译：一种用于反应注射成型的链增长剂（RIM），其包含丁二醇的正常液体共混物和用吸电子基团单取代的具有式“IMAGE”的甲苯二胺，其中X与氨基相邻，并且选自卤素，CN，NO 2，酰基，羧酸酯和其异构体混合物，其中丁二醇和二胺以4:1至约19:1的临界摩尔比组合。上述共混物特别可用于通过RIM或RRIM（增强反应注射成型）方法制备聚氨酯 - 聚脲弹性体的大型模制品，其中在模具中与异氰酸酯聚合之前将即时预制混合物加入到多元醇反应物和催化剂的混合物中以产生具有改进性能的氨基甲酸酯/脲聚合物产品。因此，本发明还涉及通过使用本发明的增链剂共混物和在环境温度下保持液态的多元醇反应物的混合物来增强RIM或RRIM方法和改进的产品。
