PURPOSE: Novel acrylic synthetic yarn having high flame retardance, improved gloss and transparency, consisting of a polymer comprising acrylonitrile and a vinyl monomer copolymerizable with it, containing an inorganic tin compound having a specific particle diameter. n CONSTITUTION: A polymer reaction mixture obtained by subjecting acrylonitrile and a vinyl monomer copolymerizable with it to emulsion polymerization, etc. is blended with a tin compound (preferably water-soluble tin compound to become gelatinous precipitation or colloidal state by dilution with water, etc.). The polymer is then separated, purified, blended with a solvent, spun, and the prepared yarn has 0.1W8wt% calculated as metal tin content of inorganic tin compound having ≤100mμ average particle diameter, to give the desired yarn. n USE: Curtains, carpets, toys, etc. n COPYRIGHT: (C)1984,JPO&Japio |
