Abstract: A flame retardant linear polyester comprising the product of a polyethylene terephthalate prepolymer, bis-hydroxy alkyl bibenzoate and a flame-retarding amount of a carboxy-phosphinic acid, a process for producing the polyester and products produced from the polyester are disclosed.

Abstract: A flame retardant linear polyester comprising the product of recycled polyethylene terephthalate, bis-hydroxy alkyl bibenzoate and a flame-retarding amount of a carboxy-phosphinic acid, a process for producing the polyester and products produced from the polyester are disclosed.

Abstract: A vinyl composition tile formulation is disclosed which comprises polyvinyl chloride, inorganic fillers and from about 0.5% to about 4%, by weight of said formulation, polyvinyl butyral, as a tackifier.

Abstract: New compounds including bis-.beta.-hydroxy ethyl bibenzoate containing less than 2.5%, and preferably less than 1%, diethylene glycol and a process for the production of the bis-.beta.-hydroxy ethyl bibenzoate by the condensation of 4,4'-biphenyl dicarboxylic acid and ethylene glycol at low temperature and pressure in the presence of a catalyst are disclosed. Use of the compounds to produce polyesters is also disclosed.

Abstract: Certain (1,3,2-dioxaphosohorinanemethan) amine compounds, which are useful as halogen-free flame retardant compounds, are disclosed. The compounds are particularly useful in polyurethane compositions.

Abstract: A solid state pH sensor having an indicator electrode of metal/metal oxide and a reference electrode of metal/metal salt applied to inert, electrical conductors imbedded in an electrically non-conductive substrate, such as a ceramic substrate. The sensing portion of the sensor preferably has a coating of an annealed perfluorocarbon copolymer. Alternatively, the indicator or reference electrodes may be formed on separate electrically non-conductive substrates with each having an inert electrical conductor imbedded therein. These indicator or reference electrodes may be utilized with each other or with prior art electrodes.

Abstract: A flexible plasticized polyurethane foam is taught in which water is used as the foaming agent and a plasticizer selected from phthalate, phosphate ester adn bezoat plasticizers is added to improve the softness and flexibility of the polyurethane.

Abstract: A catalytic process for the selective alkylation of mono- and polycyclic aromatic hydrocarbons is described. The aromatic hydrocarbon is reacted with an alkylating agent in the presence of an acid form of a dealuminated small pore mordenite catalyst having an atomic ratio Si/Al of at least 10:1 to thereby yield the desired alkyl substituted derivative with improved selectivity and improved yield.

Abstract: A sensor which may be immersed in a fluid to measure the pH and the ORP potential of the fluid is taught. The sensor has three solid state electrodes, a pH sensing electrode, a reference electrode and an ORP potential sensing electrode, which extend from a fluid-tight enclosure. The enclosure further contains a display means for indicating the pH measurement and the ORP potential measurement.

Abstract: A gray poultry nest pad is taught. The gray color is defined by the "Munsell System" comprising a hue of 2.5R through 10RP inclusive, a value of 3 through 9 inclusive and a chroma of 0 through 2 inclusive.

Abstract: A passive metal is coated with a perfluorocarbon copolymer cation-exchange polymer and subsequently annealed. The annealed polymer coating acts as a barrier to anions which attack and breakdown the passivity mechanism of such passive metals, thereby protecting the passive metals against localized corrosion, such as crevice or piting corrosion, caused by anionic attack.

Abstract: A dentifrice composition is disclosed which contains dicalcium phosphate dihydrate and other common ingredients and a zinc sodium tripolyphosphate compound.

Abstract: A dentifrice composition is disclosed which contains an effective amount of a zinc-alkali metal tripolyphosphate compound for the control of dental plaque and dental calculus.

Abstract: A process for recycling waste paper is disclosed in which an alkali metal Kurrol's salt, preferably potassium Kurrol's salt, is added to the process water.

Abstract: A process for the manufacture of paper and paper products is disclosed in which an alkali metal Kurrol's salt, preferably potassium Kurrol's salt, is added to the process water to improve the process water drainage from the paper pulp.
