Abstract: Polyester molding composition containing polybutylene terephthalate, nucleated polyethylene terephthalate or mixtures thereof as well as thermally stable reinforcing fibers and polyphenylene sulfide having a melt flow rate of less than about 1,000.

Abstract: Poly(C.sub.2 -C.sub.4 alkylene terephthalate) molding composition containing aromatic polyester carbonate and impact modifier. The aromatic polyester carbonate is derived from a dihydric phenol, a carbonate precursor and dicarboxylic acid or ester forming derivative thereof. The impact modifier may be a core-shell polymer polymerized from monomers comprising butadiene or may be a core-shell polymer having a first elastomeric phase polymerized from a monomer system including C.sub.1 -C.sub.6 alkylacrylate as well as crosslinking and graftlinking monomers and having a final rigid thermoplastic phase polymerized in the presence of the elastomeric phase.

Abstract: Poly(C.sub.2 -C.sub.4 alkylene terephthalate) molding composition containing aromatic polyester and impact modifier. The aromatic polyester is a linear aromatic polyester consisting essentially of bisphenol and dicarboxylic acid monomer components. The impact modifier may be a core-shell polymer polymerized from monomers comprising butadiene or may be a core-shell polymer having a first elastomeric phase polymerized from a monomer system including C.sub.1 -C.sub.6 alkylacrylate as well as crosslinking and graftlinking monomers and having a final rigid thermoplastic phase polymerized in the presence of the elastomeric phase.

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.
