摘要 |
A process for preparing copolymers which comprises copolymerizing (A) at least one ethylenically unsaturated dicarboxylic anhydride derived from at least one dicarboxylic acid having 4 to 8 carbon atoms, (B) at least one vinylaromatic compound, and (C) optionally at least one non-(A) ethylenically unsaturated comonomer containing at least one heteroatom, (D) reacting the copolymer with at least one compound of the formula I a or I b where A<SUP>1 </SUP>is C<SUB>2</SUB>-C<SUB>20 </SUB>alkylene, identical or different, R<SUP>1 </SUP>is C<SUB>1</SUB>-C<SUB>30 </SUB>alkyl, linear or branched, and n is an integer from 1 to 200, hydrolyzing the product with water or an aqueous alkaline solution, and subsequent to hydrolysis adding further free-radical initiator. |
