  Polymers containing polyalkylpiperidines and use thereof as stabilizers for synthetic polymer compositions are described. In said polymers, sterically hindered polyalkylpiperidines are linked in the main chain via bridging members containing 2-hydroxy-1,3-trimethylene groups, or derivatives thereof. 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 polyaikylpiperidine-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.

  本发明描述了含有聚烷基哌啶的聚合物及其作为合成聚合物组合物稳定剂的用途。 在所述聚合物中，立体受阻的聚烷基哌啶通过含有 2-羟基-1,3-三亚甲基基团或其衍生物的桥接构件连接在主链上。 这种聚合物的显著特点是在各种合成聚合物组合物（如聚烯烃）中具有更好的稳定效果，可防止光和/或热引起的劣化。 本发明中含有聚烷基哌啶的聚合物在热加工或含有所述聚合物的成型物品储存期间几乎不挥发，并且耐溶剂萃取。

  Disclosed is a curable composition capable of producing a cured product having excellent heat resistance and low outgassing properties. In particular, the curable composition comprises an epoxy compound represented by formula (1): wherein R 1 to R 4 , R 7 to R 12 , and R 15 to R 18 are each independently selected from the group consisting of hydrogen, an alkyl group, and an alkoxy group; R 5 , R 6 , R 13 , and R 14 are each independently selected from the group consisting of hydrogen, an alkyl group, and an alkoxy group; with the optional exception that one of R 5 or R 6 and one of R 13 or R 14 forms a cross-linked structure represented by —CH 2 —, and n is an integer of 0 or 1, and a cationic polymerization initiator containing a Lewis acid and a Lewis base.
