FIRE RETARDANT POLYOLEFIN FIBERS AND FABRICS.

摘要

A flame-retarded polyolefin fiber made of a thermoplastic polyolefin and a graft copolymer composition represented by tile formula: in which PP is polypropylene, and S represents grafted side chains having halogenated monomeric units of the formula: wherein x=1 to 4, R8 is H or CH3, R9 is H or a C1-4 alkyl group, and R10 is Br or Cl. In an alternate embodiment the flame-retarded polyolefin fiber further includes a halogenated bisphenol derivative represented by the formula: in which R1 to R4 are H, CH3 or a halogen, R5 is H, dihaloethyl, dihalopropyl or dihalobutyl, and A is a single bond, O, CO, S, SO2 or C(R6)(R7), where R6 and R7 are H or a C1-4 alkyl.
