PHOTOACTIVE EPOXY COMPOUND AND PREPARATION METHOD THEREOF

摘要

PURPOSE: Photoactive epoxy compound and preparation method thereof are provided to excellent thin-film processing having high adhesive strength, low coefficient of thermal expansion, excellent heat stability and size stability. CONSTITUTION: This photoactive epoxy compound having below chemical formula(I) structure is prepared by reacting compound(HO-X-OH) n+1 mole substituted with hydroxyl group in both ends of molecular group X with epichlorohydrin n+2 mole. In chemical formula(I), wherein X expresses molecular group to make cycloaddition reaction in double bonding part that exists in the inside by irradiate ultraviolet rays, n expresses integral of 0 to 40 as repeat unit.
