    • The present invention relates a process for the production of polyurethanes wherein a tertiary amine functionality is incorporated into the side chain of a diaminobenzoate, to form a non-fugitive catalyst polyurethane chain extender. These non-fugitive chain extenders are polyurethane catalysts that provide adequate cure without residual odor and safety hazards associated with the more traditional tertiary amine catalysts. When reacted with the isocyanate reactive group the non-tertiary amine portion of the chain extender is bound to the polymeric network. Diffusion of the catalyst species from the polyurethane has been prevented, thus negating odor and toxicity as a problem. The diaminobenzoate provides enhanced polyurethane physical properties.
    • 本发明涉及生产聚氨酯的方法,其中叔胺官能团被并入二氨基苯甲酸酯的侧链中,以形成非逸散催化剂聚氨酯增链剂。 这些非逸散性增链剂是聚氨酯催化剂,其提供足够的固化而没有残留的气味和与更传统的叔胺催化剂相关的安全危害。 当与异氰酸酯反应性基团反应时,扩链剂的非叔胺部分与聚合物网结合。 已经防止了催化剂物质从聚氨酯中的扩散,因此不利于气味和毒性问题。 二氨基苯甲酸酯提供增强的聚氨酯物理性能。
