Abstract: Liquid antimony organic sulfur-containing compounds are rendered stable at ambient conditions by incorporating an effective amount of an ethoxylated organo phosphate ester. The stable liquid compositions contribute to the stability of vinyl halide resins.

Abstract: A vinyl halide resin stabilizer composition which essentially contains:(a) a calcium, zinc or mixed calcium/zinc salt of a higher fatty acid; and(b) a polyhydroxy alcohol component wherein at least 50% of this component is either di-or tri-pentaerythritol.These compositions synergistically contribute to the heat stability of vinyl halide resin compositions and offer significant heat stabilization economies. Early color as well as long term heat stability performances of the metal salt compounds are improved in the compositions disclosed thereby permitting the reduction in amounts of such compounds needed for stabilization.

Early color as well as long term heat stability performances of the metal salt compounds are improved in the compositions disclosed thereby permitting the reduction in amounts of such compounds needed for stabilization.

Abstract: Flame retardant latex bases having an excellent balance of properties are prepared most efficiently and economically by blending together two separately polymerized latexes of different types, the polymeric content of one of said latexes being formed predominantly from a monomer mixture consisting of from about 70 to about 92% by weight vinylidene chloride and 8 to 30% by weight of certain polar comonomers principally of the lower alkyl acrylate class while the polymeric content of the second latex is formed from a monomer mixture consisting predominantly of styrene and butadiene. This technique of producing the desired flame retardant latex bases by combining two separately prepared but simpler component latexes not only maximizes quality control and manufacturing flexibility but also permits the simultaneous realization of higher conversions and reduced polymerization cycles or residence times so that productivity is also maximized.

Abstract: A propylene polymer composition having excellent affinity towards basic dyestuffs is produced by blending a propylene polymer with an alternating copolymer of an alkyl vinyl ether and maleic anhydride, the alkyl group of the alkyl vinyl ether containing at least 8 carbon atoms.
