Abstract
The invention relates to compounds obtainable by polymerization of esters or phenol ethers of the formula V ##STR1## and/or of the formula VI ##STR2## in which m and n are each 0 or 1, and A, E, R.sup.1 to R.sup.6 and X are as defined in claim 1, and up to 50 mol % of other, ethylenically unsaturated compounds. The homopolymers and copolymers according to the invention can advantageously be employed for the stabilization of organic polymers against the harmful effect of light, oxygen and/or heat.
