ABSTRACT:
The invention relates to polyethers containing recurring units of the formula I ##STR1## in which A is --CH.sub.2 -- or --CO--, and, when A is methylene, E is ##STR2## and when A is carbonyl, E is ##STR3## R.sup.1 is hydrogen, and R.sup.2 is likewise hydrogen or an aromatic, aliphatic or araliphatic carbonyloxy radical or a corresponding radical of an ether or tertiary amine, or R.sup.1 and R.sup.2 together are a.dbd.O substituent or together with the carbon atom to which they are bonded are a five- or six-membered, substituted, oxygen- and/or nitrogen-containing heterocyclic ring, and
R.sup.17 is a hydrocarbon radical having a maximum of 18 carbon atoms.
The polyethers according to the invention can advantageously be employed for the stabilization of organic material against the harmful effect of light, oxygen and/or heat.
