MONOMER FOR INSULATING MATERIAL USED IN ALUMINUM TECHNOLOGY AND COPPER TECHNOLOGY

摘要

PROBLEM TO BE SOLVED: To obtain a new starting material for forming an insulating polymer which has a small dielectric constant, high-temperature stability, and chemical stability.;SOLUTION: A new bis-o-aminophenol is expressed by formula I (M is a bivalent residue having a specified structure). Heat-resistant polybenzoxazole is formed out of the bis-o-aminophenol. The bis-o-aminophenol is preferably produced by nitrosating a diol which corresponds to the aminophenol to form a nitroso compound, and hydrogenating the nitroso compound with H₂ in the presence of Pd/C, so as to obtain the amino compound by reduction.;COPYRIGHT: (C)2004,JPO
