A curable resin composition, which comprises a resin formed, in the presence of a transition metal complex, by polymerizing an oxidative-polymerizable compound that contains a phenol-compound-containing vegetable oil. A method for producing a curable resin composition comprising a resin formed, in the presence of a catalyst, by polymerizing an oxidative-polymerizable compound that contains a phenol-compound-containing vegetable oil, wherein the catalyst is a transition metal complex. The curable resin composition is useful as a raw material for a urushi-like coating, a friction material, a brake lining material, a brake pad material, a material for forming a coating film, a compound for a recording material, a raw material for an ink, a raw material for a coating,.a raw material for a adhesive, a raw material for an epoxy resin, a raw material for a photoresist or antioxidant, and a starting material for a functional polymer.

Resin composition and process for producing the same

The present invention provides a curable resin compound which is soluble in organic solvents and easy to use, and a method for producing the same. The curable resin compound comprises a structure and crosslinkable groups which end-cap the structure, the structure comprising three or four non-substituted benzene rings each of which is joined with each adjacent benzene ring by an ether or ketone linkage so that both types of linkages are present in the structure. Though the curable resin compound exhibits satisfactory solubilities in organic solvents, a composition comprising the compound can be cured by a crosslinking reaction to be insoluble in the organic solvents while being provided with improved solvent resistance and chemical resistance. Accordingly, the present invention also provides a cured-resin material derived from the aforementioned curable resin compound, the cured-resin material being excellent in solvent resistance, chemical resistance and thermal resistance.

In a method for ring opening polymerization in which the polymerization proceeds with the ring opening of a cyclic compound as a monomer, a hydrolase is used as a catalyst.

Method for ring opening polymerization using a hydrolase catalyst

A copolymer of the present invention is produced by copolymerization of an electron-donating monomer having an electron-accepting group and an electron-accepting monomer having an electron-accepting group. The copolymer thus exhibits a high dielectric constant, a low level of hygroscopicity and good adhesion.
