Abstract: In a first aspect, an article includes an inorganic substrate and a polymer film layer. The inorganic substrate includes a material including a ceramic, a glass, a glass-ceramic or a mixture thereof. The material includes a metal cation selected from the group consisting of silicon, aluminum, titanium, zirconium, tantalum, niobium and mixtures thereof and oxygen. The polymer film layer includes a polymer including an imide group. From an interface where the inorganic substrate contacts the polymer film layer, a line-profile of a CNO? signal from negative secondary ion mass spectroscopy decreases as it moves away from the interface and into the bulk of the polymer film layer.

Abstract: In a first aspect, a polymer composition includes a first polymer derived from a soluble polymer composition having an imide group and a Tg reducing compound having an amine group. The first polymer has a glass transition temperature that is lower than a second polymer derived from the same soluble polymer composition, but without a Tg reducing compound having an amine group. In a second aspect, a coating solution includes a soluble polymer having an imide group and a Tg reducing compound having an amine moiety that can be an amine or a first masked amine that can be converted to an amine, wherein the first masked amine can be chemically converted, thermally converted, photo-converted or dissociated.
