Abstract
A process for preparing a flame-retardant antistatic polymer additive useful for incorporation into the melt prior to extruding fibers or other polymers or for dispersing on fibers. Improved flame-retardant properties are obtained by including with said flame-retardant additive an effective flame-retardant proportion of a compound from group Vb of the periodic table.
Claims10
A method of preparing a flame-retardant, antistatic synthetic polymer fiber comprising a synthetic polymer fiber and the reaction product of
- (a) a polyoxyalkylene compound containing oxyethylene and oxypropylene groups or polyester thereof and
- (b) a halogenated reactant selected from the group consisting of at least one of an aliphatic or aromatic diacid, or acyl halide derivative thereof and a diol and
- wherein said polyoxyalkylene compound is a conjugated polyoxyalkylene compound obtained by block polymerization or heteric polymerization and having as a nucleus a nitrogen-containing reactive hydrogen compound, said process consisting of the step of dispersing about 0.1 percent to about 12 percent by weight of said polymer in or on said fibers.
