Abstract

A process for preparing a flame resistant polymeric polyblend composition, characterized in that (A) a latex containing a monovinylidene aromatic monomer polymer, in which the rest of ethylenically unsaturated nitrile monomer ranges from 0 to 90% in By weight of the polymer, a latex of a crosslinked polychloroprene rubber is mixed with (B) having a particle size ranging from 0.7 to 4.0 microns and a Mooney viscosity of at least 200, which is grafted with: (1) at least one aromatic monovinylidene monomer and (2) a residue of ethylenically unsaturated nitrile monomer ranging from 0 to 90% by weight of the grafted polymer, wherein the percentage grafting of aromatic monomer and nitrile monomer onto said rubber of polychloroprene is in the range of 10 to 100% by weight, based on the weight of said polychloroprene rubber, (C) coagulating said mixture, (D) separating the solids, (E) drying said solids, (F) dry mixing said solids with 1 to 15% by weight, based on the total weight of the polyblend, of an inorganic compound of Sb2O3, Bi2O3, MoO3, SnO2, WO3 or mixtures thereof, (G) subjecting said mixture Dried to a mechanical lock in which the melting temperature of said polyblend is reached and said rubber of said inorganic compound is uniformly dispersed in the polyblend melt, and (H) cooling the polyblend to a solid form followed by grinding of said polyblend solid to the required size.
