The fusibility terminal modification imido oligomer, and the varnish, and its hardened material, and its imido prepreg, and is superior in heat resistance the fiber-reinforced laminate which use the 2 phenyl 4,4' - diamino diphenyl ether

摘要

Topic This invention, dissolved for the organicity solvent, such as solution retention stability and the new terminal modification imido oligomer which melting viscosity is superior low in compactibility, and dissolving those in organicity composition, heat of heat resistance, elastic modulus, stretch breaking strength and the stretch breaking elongation etc which were created making use of the varnish, and the terminal modification imido oligomer which become and designates that the hardened material, and the prepreg, and the fiber-reinforced laminate whose mechanical property are high are offered as purpose.SolutionsThe fusibility terminal modification imido oligomer of this invention is displayed with general expression (1).(In formula, R and R display the aromatic diamine residue of the divalent, R and R display the aromatic tetracarboxylic acids residue of 4 value. R and as for R being the hydrogen atom or the phenyl group, in each case one side displays the phenyl group. m and n, m 1, n 0, 1 m+n 20 and 0.05 m/(m+n) satisfies the relation of the 1, array of the iteration unit may be either block or random.)
