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&#x2032; represents a hydrogen atom); and Ar represents a divalent organic group containing an aromatic ring and/or a heterocyclic ring).

Film-forming composition

There is provided a resist underlayer film having heat resistance that is used for a lithography process in the production of semiconductor devices, and a high refractive index film having transparency that is used for an electronic device. A polymer comprising a unit structure of Formula (1): wherein each of R, R, R, and Rmay be a hydrogen atom, Rmay be phenyl group or naphthyl group. A resist underlayer film forming composition comprising the polymer, and a resist underlayer film formed from the composition. A high refractive index film forming composition comprising the polymer, and a high refractive index film formed from the composition.

Carbazole novolak resin

A method for producing a highly branched polymer, with which a molecular weight can be controlled without using a polymerization inhibitor and a polymer having a controlled molecular weight can be produced safely even in a case of mass production in an industrial scale. A method for producing a highly branched polymer including polymerizing a monomer A having two or more radical polymerizable double bonds in a molecule, in the presence of a polymerization initiator B in an amount of 5% by mol to 200% by mol with respect to 1 mol of the monomer A at a temperature 20&#xb0; C. higher than a 10-hour half-life temperature of the polymerization initiator B or higher.

Method for producing highly branched polymer

There is provided a method for producing a succinimide compound. The method for producing a succinimide compound of formula (3) comprises reacting an aminomalonic ester compound of formula (1) with a compound of formula (2) in a solvent in the presence of a base, wherein an alcohol is used as the solvent and an alkali metal alkoxide is used as the base. (where Rand Rindependently represent an alkyl group having 1 to 12 carbon atom(s) which may be a straight chain, branched or cyclic, etc., Rand Rindependently represent a hydrogen atom, etc., Rrepresents an alkyl group having 1 to 12 carbon atom(s) which may be straight chain, branched or cyclic, etc.).
