  According to the invention there are obtained modified polyurethanes which have a durable, wash-fast, acid-resistant, cleaning-resistant and solvent-resistant stabilization on the basis of 2,2,6,6-tetraalkyl-piperidine light protective agents. The stabilizers are integral constituents of the polyurethanes, that is to say they are built into the polyurethane chain by a chain lengthening reaction in which two H-active reactive groups (preferably from the series of primary or secondary amino groups, carboxylic acid hydrazide, carbazic ester or semicarbazide groups) of a 2,2,6,6-tetraalkyl piperidine derivative react with isocyanate groups of polyisocyanates or isocyanate prepolymers, optionally in the presence of the usual chain lengthening agents.

  根据本发明，基于2,2,6,6-四烷基哌啶光保护剂，通过链延伸反应，将两个H活性反应基（优选为一级或二级氨基、羧酸肼、氨基脲酯或半脲酸基）的2,2,6,6-四烷基哌啶衍生物与聚异氰酸酯或异氰酸酯预聚物的异氰酸酯基反应，可选地在通常的链延伸剂的存在下，得到改性聚氨酯。该稳定剂是聚氨酯的组成部分，即它们被内置于聚氨酯链中，具有耐久、耐洗涤、耐酸、耐清洁和耐溶剂的稳定性。

  This invention relates to permanently stabilized polymers containing substituted piperidine derivatives chemically attached to the polymer molecule through O- or N-atoms. Compounds based on 2,2,6,6-tetraalkyl piperidines have now been found which, on the one hand, have a very high stabilizing activity and, on the other hand, contain one or more reactive groups through which they are able to react with the polymers to be stabilized. Stabilized polymers, preferably polyurethane elastomer filaments, films and coatings with a permanent washing-resistant, boiling resistant, acid-resistant, dry-cleaning-resistant and solvent-resistant stabilization based on 2,2,6,6-tetraalkyl piperidine light stabilizers are thus obtained.

  本发明涉及一种永久稳定的聚合物，其中含有通过O-或N原子化学连接到聚合物分子上的取代哌啶衍生物。现已发现基于2,2,6,6-四烷基哌啶的化合物，一方面具有非常高的稳定活性，另一方面通过其中一个或多个反应性基团能够与待稳定的聚合物发生反应。因此，基于2,2,6,6-四烷基哌啶光稳定剂，可以获得具有永久耐洗、耐沸水、耐酸、耐干洗和耐溶剂稳定性的稳定聚合物，特别是聚氨酯弹性体丝、膜和涂层。
