PRODUCTION OF FLAME-RETARDANT ACRYLONITRILE SYNTHETIC FIBER

摘要

PURPOSE: To enable simple production of flame-retardant acrylonitrile (AN) fiber by melt-extruding an AN copolymer containing vinyl chloride and/or vinylidene chloride as an essential comonomer using water as a plasticizer without requirig an organic solvent. ;CONSTITUTION: An AN copolymer containing vinyl chloride and/or vinylidene chloride as essential comonomers is melt-extruded into fibers using water as a plasticizer. When more than 0.4wt.% of a flame retarder is added to a molten mixture of the AN copolymer with water, the flame retardancy of the fiber is improved.;COPYRIGHT: (C)1996,JPO
