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.
