Abstract
The invention relates to a composition of matter which comprises A) from 95 to 99.9 % by weight of a copolymer of acrylonitrile, a vinyl and/or vinylidene halide and, optionally, at least one other copolymerisable compound; and B) from 0.1 to 5 % by weight of a substantially water-insoluble complex antimony compound containing amide groups, the complex antimony compound being obtainable by esterifying an .alpha.-hydroxy polycarboxylic acid with a polyol, reacting the esterification product with an antimony oxide in a polar organic solvent adding a monoisocyanate to the resulting solution in such a quantity that the free carboxyl groups are converted into the corresponding amide groups, and a process for the production of these compositions of matter.
