ABSTRACT:
This invention relates to a method of producing a flame-retardant acrylic polymer by polymerizing, in the presence of a radical polymerization initiator, a vinyl monomer containing acrylonitrile in an amount of more than 75 weight %, in an aqueous medium in which is present a halogen-containing polymer latex substantially free from an emulsifier. The acrylic polymer can provide flame-retardant shaped products, especially fibers, which have no problems in the operation of spinning, transparency, gloss, dyed color clearness, etc.
