PROCÉDÉ DE PRÉPARATION D'UN COPOLYMÈRE DE POLY(ÉTHER D'ARYLÈNE) COMPRENANT DES MOTIFS D'ISOHEXIDE ET COPOLYMÈRE DE POLY(ÉTHER D'ARYLÈNE) PRÉPARÉ AINSI

摘要

The present invention relates to a method for preparing a polyarylene ether copolymer comprising isohexide units and a polyarylene ether copolymer prepared thereby and, more particularly, to an ultra-high molecular weight polyarylene ether copolymer comprising isohexide units by comprising a procedure of adding a crown ether-based compound, and to a method for preparing a polyarylene ether copolymer prepared therefrom.
