4-dihydroxybenzene dihydrochloride_Kain Industrial Additive

Background and overview[1][2] Diaminodihydroxybenzene can be used as a monomer for the preparation of polybenzoxazole, by combining 2,5-diamino-1,4-dihydroxybenzene dihydrochloride with diacid, dicarboxylic acid halide, dihydrobenzene Polybenzoxazole can be produced by reacting esters or dinitriles. In order to obtain a high molecular weight polybenzoxazole that can be effectively spun into suitable fibers, a very pure starting…
