摘要:
A polymer containing a repeating unit structure having a triazine ring such as, for example, that which is represented by formula (25): can exhibit alone high heat resistance, high transparency, high refractive index, high solubility and low volume shrinkage; and can be used as a component in a film-forming composition as appropriate.
摘要:
A polymer containing a triazine ring-containing repeating unit structure represented by, for example, formula (23) or (24), which alone can achieve high heat resistance, high transparency, high refraction index, high solubility and low volume shrinkage, without adding a metal oxide.

摘要:
A film-forming composition is characterized by containing: a triazine ring-containing hyperbranched polymer containing a repeating unit structure represented by formula (1); and a dissolution-enhancing agent for breaking a hydrogen bond formed at least within the hyperbranched polymer and/or between molecules, between a nitrogen atom in the triazine ring, and a diarylamine-derived NH group. The film-forming composition has excellent dissolvability in organic solvents such as resist solvents, and has good handling and filtration properties at low viscosity. (In the formula, R and R′ each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group (however, at least one of R and R′ represents a hydrogen atom); and Ar represents a divalent organic group containing an aromatic ring and/or a heterocyclic ring.)

摘要:
Disclosed is a triazine ring-containing hyperbranched polymer containing a repeating unit structure represented by the expression (1). By this means, it is possible to achieve a triazine ring-containing polymer which, alone, has high heat resistance, high transparency, high refractive index, high light resistance, high solubility, low volume shrinkage without adding metal oxides; and also a membrane-forming composition containing the same. In the formula, R and R′ represent independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and A represents an alkylene group optionally having a branched or alicyclic structure of 1 to 20 carbon atoms.

摘要:
A film-forming composition including a triazine ring-containing hyperbranched polymer with a repeating unit structure indicated by formula (1), and inorganic micro particles is provided. This enables the provision of a film-forming composition capable of hybridizing without reducing dispersion of the inorganic micro particles in a dispersion fluid, capable of depositing a coating film with a high refractive index, and suitable for electronic device film formation. (In the formula, R and R′ are mutually independent and indicate a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and Ar indicates a divalent organic group including either an aromatic ring or a heterocyclic ring, or both.)
摘要:
Chemically modified carbon nanotubes composed of carbon nanotubes (such as multiwall carbon nanotubes) having carboxyl groups on the surface thereof and polymeric aniline (such as 3- to 300-meric aniline) bonding thereto through the amide linkage. The chemically modified carbon nanotubes exhibit good affinity with organic solvents and readily disperse into organic solvents.
