Spinning epoxide containing acrylics into baths containing polyhydroxyls

摘要

A fiber forming composition comprising acrylonitrile and an epoxide-containing vinyl monomer is herein described wherein the epoxide portion of said monomer is pendant to the polymer chain and thereafter reacted with a polyhydroxyl compound to produce an improved filamentary material. The novel process turns upon forming an epoxide-containing polymer of acrylonitrile and allowing the polymer to undergo an acid-catalyzed reaction in a spin bath containing a polyhydroxyl compound such as polyethylene glycol. The novel compositions herein described have enhanced properties.
