    • Polyurethanes are made by reacting a polyisocyanate with a compound containing at least two isocyanate-reactive hydrogen atoms having a molecular weight of from 400 to 10,000 in the presence of a catalyst containing tertiary amino groups. The required catalyst corresponds to the formula ##STR1## in which R, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 represent a specified group or radical. A blowing agent and/or stabilizer and/or chain extending agent and/or other additives commonly used in the production of polyurethanes may optionally be included in the reaction mixture. The catalyst employed in the process is particularly advantageous in that it does not have a noticeable amine odor.
    • 聚氨酯通过使多异氰酸酯与含有至少两个分子量为400至10,000的异氰酸酯反应性氢原子的化合物在含有叔氨基的催化剂存在下反应而制备。 所需的催化剂对应于其中R,R 1,R 2,R 3,R 4,R 5,R 6和R 7表示指定基团或基团的式“IMAGE”。 在制备聚氨酯中通常使用的发泡剂和/或稳定剂和/或增链剂和/或其它添加剂可任选地包括在反应混合物中。 在该方法中使用的催化剂特别有利的是它不具有明显的胺气味。

    • The present invention is directed to a process for the production of optionally foamed polyurethanes which are combined or fabricated with another material, comprising reacting compounds with molecular weights from 400 to 10,000 containing at least 2 isocyanate reactive hydrogen atoms with polyisocyanates in the presence of catalysts containing tertiary amino groups and combining or fabricating the resulting polyurethane with another material, characterized in that the catalysts used are diffusion resistant aminoalkanols corresponding to the general formula ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 may be identical or different and represent hydrogen or a C.sub.1 -C.sub.6 alkyl group,R.sup.5, R.sup.6, R.sup.7 and R.sup.8 may be identical or different and represent a C.sub.1 -C.sub.6 alkyl group or together form a C.sub.2 -C.sub.6 alkylene group which may contain hetero atoms such as O or NR (R=C.sub.1 -C.sub.4 alkyl), and n and m may be identical or different and represent integers from 1 to 6.
