Patent number: 4837400Abstract: Polyoxymethylene molding materials having improved heat stability and consisting of(A) one or more polyoxymethylene homopolymers and/or copolymers and(B) one or more antioxidants having a sterically hindered phenolic structure,(C) with or without additives, contain(D) as an additive, one or more alkaline earth metal silicates and/or alkaline earth metal glycerophosphates, advantageously in an amount of from 0.002 to 2.0% by weight, based on the weight of component (A),for improving the heat stability, reducing the tendency to discoloration and minimizing the free formaldehyde content.To prepare the novel polyoxymethylene molding materials, the components are advantageously melted in an extruder at from 150.degree. to 260.degree. C.The polyoxymethylene molding materials are useful for the production of films or, preferably, moldings, which are used, for example, in the automotive, electrical appliances and electronics industries.Type: GrantFiled: February 4, 1988Date of Patent: June 6, 1989Assignee: BASF AktiengesellschaftInventors: Manfred Walter, Wilhelm Schuette, Heiner Goerrissen

Patent number: 4803231Abstract: Coherent thermoplastic aggregates with very high content of pulverulent mineral materials, said aggregates comprised of the said mineral materials, further of polyolefin polymers and/or copolymers, and possibly additionally of miscellaneous known additives; characterized in that, with the aim of achieving a density near to or at most equal to the theoretical density of the pulverulent mineral materials entering into their composition, while still having excellent compatibility with the polymers of redispersion, i.e., the polymers into which the subject aggregates are to be mixed, the interparticle voids between the grains of the mineral materials, which grains are basically in contact with each other, are at most filled--in the presence of a fluidifacient agent--by at least one polyolefin polymer and/or copolymer having a fusion temperature and/or softening temperature at least equal to 60.degree. C., and having a fluidity index (ASTM 1238) of at least 50.Type: GrantFiled: October 29, 1985Date of Patent: February 7, 1989Assignee: Pluess Staufer A. G.Inventors: Henri Seinera, Patricia Luberne, Claude Stock, Patrick Trouve

Patent number: 4795768Abstract: A mineral-filled thermoplastic composition is disclosed which comprises polyethylene or an ethylene-vinyl acetate compolymer; a mineral filler consisting, in the case of polyethylene, of aluminum trihydrate, magnesium hydrate, calcium carbonate or calcium/magnesium carbonates, and, in the case of the ethylene-vinyl acetate copolymer, barium titanite or neodymium titanate; and, in the case of polyethylene, an impact promoter consisting of tri(2-ethylhexyl) phosphate, isostearic acid or dodecylpyridinium salts, the selection of the impact promoter being dependent upon the mineral filler being employed, and, in the case of the ethylene-vinyl acetate copolymer, an amount of isostearic acid sufficient to increase the ductility of the composition; also disclosed is an additive composition for a thermoplastic composition which comprises a hydrophobic agent and an impact promoter.Type: GrantFiled: December 3, 1986Date of Patent: January 3, 1989Assignee: Union Carbide CorporationInventors: Fred H. Ancker, Arnold C. Ashcraft, Jr.
