The invention relates to a polymer composition (P), comprising at least one acrylonitrile-butadiene-styrene copolymer (A) (ABS copolymer (A)), characterized in that the polymer composition (P) has a surface energy of >38 dyne/cm. The invention further relates to a process for painting a surface of a polymer moulded article comprising the polymer composition (P), wherein no pre-treatment of the surface of the polymer moulded article, such as primer coating, is required prior to the application of the paint.

The invention features a hot melt composition in the form of a film including from 40% by weight to 80% by weight of a non-functionalized alkyl acrylate, from 14% by weight to 50% by weight of an olefin polymer, from 2% by weight to 15% by weight of a first functionalized polymer comprising a functional group selected from the group consisting of epoxides and carboxylic anhydrides, and from 2% by weight to 15% by weight of a second functionalized polymer comprising a functional group capable of reacting with the functional group of the first functionalized polymer.

The hot melt composition in the form of a film has found utility as an encapsulant for thin film photovoltaic modules.
