SYNTHESES OF ALTERNATING COPOLYMER FROM FURANE DICARBOXYATE, DIAMINE, AND ADIPIC ACID

摘要

The present invention relates to a preparation method of furane-based copolyamide. More particularly, the preparation method prepares a diamine monomer including a structure of furane by conducting a reaction between at least one kind of furane-based dicarboxylic acid ester and aliphatic diamine on a main chain through solid polymerization, and conducts a reaction of the diamine monomer with an aliphatic dicarboxylic acid compound. The furane-based copolyamide synthesized according to the present invention has molecular weight and color at the level which can be practically applied to industries, and can replace fuel raw materials by having excellent thermal stability, thereby being useful as an eco-friendly bioplastic.
