Abstract
The invention relates to a polybutylene polymer or oligomer which contains in its molecule at least one acryl group, said polybutylene being prepared by reacting (A) an anhydride-functional polybutylene, or derivative thereof, with (B) an acryl-functional compound having at least one hydroxyl-containing group, chlorine, isocyanate group, epoxy group or amine group in its molecule.
