Abstract
Process for preparing a macromonomer, in which a starting compound HC═CR—CH(R)—R—OH or HC═CR—CO—NH—R—OH, where Rand Rare each H or a linear or branched alkyl radical having from 1 to 4 carbon atoms, Ris a linear or branched alkylene, aralkylene radical which has from 1 to 20 carbon atoms and can contain one or more hydroxy groups and the radicals Rare each, independently of one another, a linear or branched alkyl, aralkyl, alkoxy or aralkoxy radical having from 1 to 20 carbon atoms and s=0-4, is, after partial deprotonation, reacted with at least one hydroxy-functional oxirane compound in the presence of an inhibitor of free-radical polymerization with opening of the oxirane ring, where the molar ratio of the molar amounts used n:nis in the range from 1:100 to 1:1. Macromonomers which can be obtained by the process, polymers which can be obtained therefrom and their use as additives in coating compositions, plastics and cosmetics.
