METHOD FOR FORMING THIN EPOXY POLYMER FILM

摘要

PURPOSE:To facilitate the production of a thin film from a high-purity epoxy polymer by heating a specific amino compound and a specific epoxy compound in a vacuum to vaporize the compounds and forming a thin polymer film on a substrate by vapor deposition polymerization. CONSTITUTION:A compound having at least one amino group in the molecule (e.g. aminoethylbenzene of formula I) and a compound having at least two epoxy groups in the molecule (e.g. dihydroxynaphthalene diglycidyl ether of formula II) are heated in a vacuum to vaporize them. The vaporized compounds are allowed to undergo a chemical reaction between the epoxy groups and the amino groups to thereby deposit as a thin polymer film on a substrate, thus giving the objective thin epoxy polymer film. This process may be conducted in such a manner that a compound having a molecular polarization is employed as at least either of the two compounds and the formation of a thin polymer film in a vacuum from the heat-vaporized compounds is performed with application of an electric field.
