Abstract: PURPOSE:To obtain the subject crystal having isotropically high strength, by orienting a specific alkyldiamine perpendicularly on a surface of a substrate, depositing a diamine and a diacetylenedicarboxylic acid by vacuum evaporation and irradiating with ultraviolet ray, etc., to effect the solid-phase polymerization. CONSTITUTION:(A) An alkyldimine of formula I (n is 8-18) (e.g., diaminodecane) is deposited on (B) a substrate such as polished glass plate by vacuum evaporation at a heating temperature of the component A of 30-110 deg.C, a substrate temperature of -30-10 deg.C and a vacuum degree of 10 -10 Torr. Thereafter, (C) a diamine of formula II (R is alkyl, aryl, etc.) and (D) a diacetylenedicarboxylic acid of formula III (R is alkyl, aralkyl, etc.) are deposited on the surface by vacuum evaporation, polymerized and then irradiated with ultraviolet ray or ionizing radiation (e.g., gamma-ray of cobalt 60) to effect the solid-phase polymerization and obtain the objective crystal.
