Abstract

Abstract Compounds of the formula ##STR1## in which R represents hydrogen or a methyl group, Y 1 represents an optionally branched alkylene radical with 1 to 6 C atoms, Y 2 represents an optionally branched alkylene radical with 2 to 8 C atoms, X denotes oxygen or an --NH-- group, R 1 and R 2 are identical or different and denote hydrogen, or an alkyl, alkenyl, cycloalkyl, cycloalkenyl, aryl, aralkyl or alkylaryl group which has 1 to 11 C atoms and is optionally substituted by one or more, hydroxyl, amino, epoxide, urethane, urea, ester or ether groups, or R 1 and R 2 together form a 3-membered to 6-membered ring, which optionally contains nitrogen, oxygen or sulphur as hetero-atoms, R 3 has the meaning of R 1 or represents a group ##STR2## or R 2 and R 3 , together with the ##STR3## group, form a 5-membered or 6-membered ring, which optionally contains oxygen as a further hetero-atom, and R 4 and R 5 are identical or different and represent hydrogen, an alkyl or alkenyl group which has 1 to 10 C atoms and is optionally substituted by halogen, or halogen, function as activators in the free radical polymerization of olefinically unsaturated monomers.
