摘要： Provided is a triazine ring-containing hyperbranched polymer comprising the repeating unit structure represented by formula (1) and having one or more triazine ring terminals, said one or more triazine ring terminals being capped with a compound that differs from the diamine compound serving as the starting material for the polymer and has at least two active hydrogen groups. In addition to the polymer itself exhibiting high heat resistance, high transparency, a high refractive index, high light resistance, high solubility, and low volume shrinkage, it is also possible to use the polymer to provide a composition for film formation capable of yielding a thick film having high hardness. (In formula (1), R and R′ each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and Ar represents a divalent organic group containing an aromatic ring and/or a heterocyclic ring.)

摘要： An aromatic polyamide, which is obtained by reacting a benzene tricarboxylic acid or a derivative thereof with a diamine compound in the presence of a terminally blocked compound having a crosslinkable group and a functional group that is reactive with a benzene tricarboxylic acid such as 1-amino-2-propanol or a derivative thereof as expressed by scheme (1), and which has a weight average molecular weight of 1,000-100,000 in terms of polystyrene as determined by gel permeation chromatography, has good solubility in organic solvents, while maintaining heat resistance and transparency. A thick film can be formed using a film-forming composition that contains this aromatic polyamide.
