  • Hydroxy-functional copolymerizable polyalkylene glycol macromonomers, their preparation and use
    Publication number: 20080097042
    Abstract: The present invention relates to a process for preparing esters of ?,?-ethylenically unsaturated carboxylic acids with polyalkylene glycols, by reacting an ?,?-ethylenically unsaturated carboxylic acid or reactive derivative thereof with a C2- to C4-alkylene oxide or a mixture of such alkylene oxides, wherein this reaction takes place in the presence of from 10 to 10 000 ppm, based on the weight of the ?,?-ethylenically unsaturated carboxylic acid used, of either 2,2,6,6-tetramethylpiperidine 1-oxyl or 4-hydroxy-2,2,6,6-tetramethylpiperidine 1-oxyl.
