TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The composition is in the form of a film. Alternatively, the composition comprises a blend of a fluoropolymer and an UV light-absorbing oligomer, where the UV light-absorbing oligomer comprises: a first divalent unit comprising a pendent UV absorbing group; and at least one of a second divalent unit represented by formula (I); or a third divalent unit represented by formula (II), and where the composition is an extruded film. The pendent UV absorbing group comprises a triazine, a benzophenone, or a benzotriazole. The first divalent unit is represented by formula (III).R1=hydrogen or methyl;V'=O or NH;X=alkylene or alkyleneoxy group having 1-10 carbon atoms and optionally interrupted by one or more -O- groups and optionally substituted by a hydroxyl group;R=alkyl having 1-4 carbon atoms;n=0 or 1; andZ=a benzoyl group optionally substituted by hydroxyl, alkyl, halogen, or hydroxyl; a 4,6-bisphenyl(1,3,5)triazin-2-yl group where each phenyl is optionally independently substituted by one or more alkyl or alkoxy groups; or a 2H-benzotriazol-2-yl group optionally substituted by one or more halogens.The UV light-absorbing oligomer is in the composition in an amount ranging from 0.5-5 wt.%, based on the total weight of the composition. The UV light-absorbing oligomer comprises the second divalent unit, and where R5 and R6 are both methyl. The fluoropolymer is present in the blend in an amount of at least 90 wt.%, based on the total weight of the blend. The blend further comprises poly(methyl methacrylate). The composition comprises a second, different UV light-absorbing oligomer in the blend, where the second UV light-absorbing oligomer comprises a divalent unit comprising a second pendent UV absorbing group and at least one of the second divalent unit or the third divalent unit, where the second pendent UV absorbing group comprises a triazine, a benzophenone, or a benzotriazole. The UV light-absorbing oligomer and the second, different UV light-absorbing oligomer are present in the composition in an amount of up to ten wt.%, based on the total weight of the composition. The composition is essentially free of volatile organic solvent. The fluoropolymer is selected from the group consisting of ethylene-tetrafluoroethylene copolymer, a tetrafluoroethylene-hexafluoropropylene copolymer, a tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride copolymer, or polyvinylidene fluoride.
