Abstract

See full text

A flame resistant polymer is obtained by reacting polyacrylonitrile with amine and nitro compounds, the polyacrylonitrile being polymerized by aqueous suspension polymerization using a redox initiator and containing an S component at an amount of 3,000 μg/g or less. A PAN-based polymer in which both yarn producing properties and flame resistance are improved can be realized.
