METHOD FOR MELT PROCESSING SULFONATED BLOCK COPOLYMERS AND ARTICLES COMPRISING OPTIONALLY AMINE MODIFIED SULFONATED BLOCK COPOLYMERS

摘要

The present disclosure provides a method for melt processing a sulfonated block copolymer in which the sulfonic acid or sulfonate functional groups are partially or completely neutralized by an amine, and to articles obtained by the method. Moreover, the shaped articles which are obtained by molding a composition comprising the neutralized sulfonated block copolymer may can be converted into shaped articles which comprise the sulfonated block copolymer(s) employed in the preparation of the amine neutralized block copolymer(s).;The present disclosure further provides a sulfonated block copolymer comprising which is modified by an amine of formula (Ia); ;wherein Het together with the nitrogen to which it is bonded represents an optionally substituted 5- or 6-membered hetero cycle.
