| 摘要 |
The present invention relates to the preparation of Omega-(dimethylisopropenylbenzylurethane) polyalkylene glycols with alpha-alkoxy or alpha-dihydroxy groups and to the use thereof as hydrolysis-stable macromonomers for the dispersion and crosslinking of polymers in which A is C<SUB>2</SUB>-C<SUB>4</SUB>-alkylene m is an integer from 5 to 900, and R is C<SUB>1</SUB>-C<SUB>20</SUB>-alkyl, C<SUB>6</SUB>-C<SUB>18</SUB>-aryl or a radical according to formula 2a, 2b, 2c, 3a, 3b or 3c which is bonded to the terminal oxygen atom of the alkoxy group (A-O) in formula 1 via the valence denoted by *, and in which A is not exclusively C<SUB>3</SUB>- or C<SUB>4</SUB>-alkylene.
