Abstract

Способ получения раствора сополимера на основе акрилонитрила - ПАН в N-метилморфолин-N-оксиде, отличающийся тем, что в качестве ПАН используют сополимер акрилонитрила с содержанием сомономеров не более 8 мас.%, а получение раствора осуществляют его твердофазным смешением с гидратом N-метилморфолин-N-оксида, содержащим 5-13.3 мас.% воды, при их соотношении, мас.%:при комнатной температуре до полной гомогенизации смеси и последующим нагреванием до 80-135°C.A method of obtaining a solution of an acrylonitrile-based PAN copolymer in N-methylmorpholine-N-oxide, characterized in that the acrylonitrile copolymer with a comonomer content of not more than 8 wt.% Is used as a PAN, and the solution is prepared by solid-phase mixing with N-methylmorpholine hydrate -N-oxide containing 5-13.3 wt.% Water, with their ratio, wt.%: At room temperature until the mixture is completely homogenized and then heated to 80-135 ° C.
