Diazaspirodecanes of the general formulae ##STR1## are reacted with epoxides or aldehydes to give alcohols and the latter are reacted with bifunctional compounds to form oligomers or polymers which can be used as light stabilizers for synthetic polymers. The alcohols can also be obtained if epoxy compounds which are substituted by the above diazaspirodecanes are converted into their formic acid esters and the latter are saponified.
通式为##STR1##的Diazaspirodecanes与环氧化物或醛类反应,形成醇类。后者与双官能团化合物反应,形成可以用作合成高分子材料光稳定剂的寡聚物或聚合物。如果将上述Diazaspirodecanes取代的环氧化合物转化为其甲酸酯,然后皂化,也可以得到这些醇类。
