• Non-fugitive diaminobenzoate catalytic chain extenders
  申请人：AIR PRODUCTS AND CHEMICALS, INC.

  公开号：EP0300349A1

  公开（公告）日：1989-01-25

  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.

  本发明涉及一种生产聚氨酯的方法，其中将三级胺功能并入二氨基苯甲酸酯的侧链中，形成一种非挥发催化剂聚氨酯链延伸剂。这些非挥发性链延伸剂是聚氨酯催化剂，可提供足够的固化，而不会产生与传统三级胺催化剂相关的残留气味和安全隐患。当与异氰酸酯反应的反应基团结合后，链延伸剂的非三级胺部分被结合到聚合物网络中。防止了催化剂物种从聚氨酯中扩散，从而消除了气味和毒性问题。二氨基苯甲酸酯提供了增强的聚氨酯物理性能。
