Abstract: Aluminum zinc phosphate hydrates or basic aluminum zinc phosphate hydrates are manufactured by reacting 1 mole of aluminum hydrogen phosphate with from 2.4 to 4 moles of zinc oxide, if necessary with the addition of up to 0.4 moles of alkali aluminate or the equivalent quantity of alkali hydroxide. A 50% by weight acidic aluminum hydrogen phosphate solution is preferably used for the reaction which is carried out at an elevated temperature in the range from 30.degree. to 80.degree. C. The aluminum zinc phosphate hydrates produced by the method are useful anti-corrosion pigments for use in paints.

Abstract: Improved thermoplastic compositions are described. These compositions exhibit low resistivities making them particularly suitable for use in electrical applications. These compositions comprise a composition of polyphenylene ether and alkenyl aromatic resins in combination with an effective amount of anti-static agent. The anti-static agent is a styrene-allyl alcohol copolymer, anionically polymerized poly(ethylene oxide) or a combination thereof.

Abstract: Improved polyphenylene ether-containing molded articles are described. These contain high molecular weight hydrogenated block copolymers of a vinyl aromatic compound and a diene. The articles exhibit excellent mechanical properties but do not exhibit the lamination as observed in similar articles containing lower molecular weight block copolymers.

Abstract: Compositions comprising a polyphenylene ether resin, an impact modifier such as an A-B-A.sup.1 block copolymer, a plasticizer and particulate titanium dioxide in which the particles have a mean particle size no greater than 0.6 micron, provide unexpected retention of Gardner impact resistance.

Abstract: Compositions comprising polyphenylene ether, an impact modifier such as an A-B-A.sup.1 block copolymer, a plasticizer and a particular clay filler in which the particles have a mean particle size of no greater than 0.6 micron, preferably between 0.1 and 0.6 micron, and a surface area of at least 15 m.sup.2 /g. The clay should be essentially free of large particles commonly known as "grit", and should also be substantially non-agglomerated or clump-free. The compositions when molded possess unexpectedly high Gardner impact resistance.

Abstract: Thermoplastic moldingcompositions having improved melt-flow characteristics and enhanced impact resistance characteristics are disclosed which comprise in intimate admixture (a) a polyphenylene ether resin, (b) a plasticizer composition, and (c) a minor amount of a hydrogenated radial teleblock copolymer of a vinyl aromatic monomer and a saturated rubber.
