Acrylonitrile-based polymer composition for forming

Abstract

Abstract PURPOSE:To obtain titled composition of outstanding water permeability and formability, with high selective material separation performance, suitable for forming hollow fiber, etc., comprising an acrylonitrile-based polymer and a specific acrylonitrile-based block copolymer. CONSTITUTION:The objective composition comprising (1) 5-50wt% of an acrylonitrile-based polymer of an acrylonitrile content >=40wt% and (2) 50-95wt% of a block copolymer composed of (A) a segment consisting of at least 80wt% of acrylonitrile and a copolymerizable vinyl monomer (e.g., acrylamide) (B) a second segment consisting of at least 20wt% of a non-cyano (pref. carboxyl) functional group-contg. vinyl monomer other than acrylonitrile (e.g., acrylamide) and a copolymerizable vinyl monomer (pref. acrylonitile).
