NEW DIAMINE COMPOUND, AND POLYAMIC ACID AND IMIDIZATION POLYMER PRODUCED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new diamine compound having a high sulfur content, becoming a raw material for producing a polyamic acid and an imidization polymer having a further higher refractive index. SOLUTION: This diamine compound is expressed by formula (1). The polyamic acid is obtained by performing the polycondensation reaction of the diamine compound expressed by the formula (1) with a tetracarboxylic acid dianhydride. COPYRIGHT: (C)2010,JPO&INPIT
