Abstract

Polyurethane-modified addition copolymers preparable by free-radically (co)polymerizing an olefinically unsaturated monomer (a) in an aqueous or nonaqueous medium comprising at least one reaction product (A/B) of(A) at least one addition copolymer containing on average per molecule at least 0.1 isocyanate-reactive functional groups and preparable by free-radical copolymerization of at least
