Polymers containing polyalkylpiperidines, preparation and use thereof as stabilizers for synthetic polymer compositions are described. In said polymers, sterically hindered polyalkylpiperidines are laterally linked to the main chain. The polymers are distinguished by an improved stabilizing effect in various synthetic polymer compositions, such as polyolefins, against light- and/or heat-induced deterioration thereof. The polyalkylpiperidine-containing polymers of the invention are hardly volatile upon heat-processing or during storage of shaped articles containing said polymers, and are resistant to extraction with solvents.
本文介绍了含有聚烷基哌啶的聚合物,以及其作为合成聚合物组合物稳定剂的制备和使用方法。在上述聚合物中,立体受阻的聚烷基哌啶与主链横向相连。这种聚合物的显著特点是能改善各种合成聚合物组合物(如聚烯烃)的稳定效果,防止光和/或热引起的劣化。本发明的含聚烷基哌啶聚合物在热加工或储存含有上述聚合物的成型物品时几乎不挥发,并且耐溶剂萃取。
