Soluble polyacrylic cyanide composite and preparation process thereof

The present invention relates to meltable polyacrylonitrile composition connecting ionic liquid as plasticizer and its preparation process. The meltable polyacrylonitrile composition is prepared with polyacrylonitrile in 72-98 wt% and ionic liquid in 2-28 wt% and through stir at 25-90 deg.c to mix. It may be molten at 120-155 deg.c, and may be used as material for polyacrylonitrile fiber, film, etc. The ionic liquid in various kinds has no toxicity and no volatility and is environment friendly.
