ABSTRACT An article constituted of two different polymers which are capable of forming compatible polymer blends, the first of which polymer components is A) a polymer P1 that is made up of at least 30 wt.% of monomers of Formula I: Image I in which R1 is hydrogen or methyl and R2 is a hydro- carbon group of 1-18 carbon atoms, and the second of which polymers is B) a polymer P2 that is made up of at least 30 wt.% of monomers of Formula II: Image II in which R3 is hydrogen, methyl, or a -CH2-X-CHR5R6 group, X is a -?-Z-, -Z-?-, or Z-?-Z'- group, with Z being oxygen or -NR4, Z' being oxygen or NR4, and R4 being hydrogen or an alkyl group of 1-12 carbon atoms, wherein -CHR5R6 stands for an aliphatic or araliphatic hydrocarbon group of 5-24 carbon atoms, said article being of such a design that one of the polymers forms a coating on the other, or one of the polymers forms a coating on a compatible polymer blend PM made up of A) 0.1 - 99.9 wt.% of a polymer P1 and B) 99.1 - 0.1 wt.% of a polymer P2.
