Abstract

The invention relates to a copolymer which can be obtained by radical copolymerisation of at least two components A and B. According to the invention, a) at least one ester of one at least difunctional carboxylic acid which has at least one olefinically unsaturated double bond is used with an alkyl oxide addition compound as component A and b) at least one additional monomer which can be subjected to radical polymerisation is used as component B. The invention also relates to a method for producing copolymers of this type and to the use thereof, in particular, to their use as a binding agent in adhesives.
