Mo3655 LeA 27,954 POLYMERS CAPABLE OF OXIDATIVE CROSSLINKING ABSTRACT OF THE DISCLOSURE The present invention relates to polymers capable of oxidative crosslinking, characterized in that they contain 10 to 80% by weight of structural units corresponding to formula (I) and/or (Ia) Image (I) Image (Ia) wherein R1 is an aliphatic saturated hydrocarbon radical containing 2 to 6 carbon atoms, provided that at least 2 carbon atoms are arranged between the nitrogen atom and the oxygen atom, and R2 at least 30% of the substituents R2 are monoolefinically or polyolefinically unsaturated hydrocarbon radicals and the remainder, i.e. up to 70% of the substituents R2, are saturated aliphatic and/or aromatic hydrocarbon radicals which may optionally contain oxygen and/or nitrogen as hetero atoms in the form of ether, ester, keto, urethane, urea and/or amide groups, provided that substituent R2 contains at least 2.0% by weight, based on the weight of the polymer, of aliphatically unsaturated double bonds, expressed as C=C (molecular weight = 24). The present invention also relates to a process for the production of these polymers and to the use of these polymers as binders or binder component for coating or sealing compositions. Mo3655
