Abstract
In a first aspect, a dicarbonyl halide includes an alicyclic group. In a second aspect, a polymer composition is derived from the dicarbonyl halide, a dianhydride and a diamine, wherein the polymer composition is a poly(amide-imide) or a poly(amide-ester-imide), wherein the poly(amide-ester-imide) is further derived from a polyol. In a third aspect, a polymer film includes the polymer composition. In a fourth aspect, an electronic device includes the polymer film. In a fifth aspect, a metal-clad laminate includes the polymer film.
