Abstract: Disclosed herein is an emulsifying composition which comprises one or more of the alkyl or alkenyl glyceryl ether phosphate compounds represented by the formula (I) and/or (II): ##STR1## in which R represents a linear saturated or unsaturated hydrocarbon group having 8-20 carbon atoms, X.sub.1 and X.sub.2 are independently a pair ion selected from the group consisting of hydrogen, alkali metal, ammonium, alkylammonium which has an alkyl group having 1-5 carbon atoms, and alkanolamine which has a hydroxyalkyl group having 2 or 3 carbon atoms.The above emulsifying composition is high in safety against skin and can be widely used in either type of W/O or O/W emulsion.

Abstract: A process for producing particles having an increased particle diameter from a powder of a polyolefin resin, which comprises heating the polyolefin resin powder at a temperature higher than the melting point of the resin in a dispersion medium in the presence of a dispersing agent and a surface-active agent.

Abstract: An easily cross linkable fluorine-containing polymer comprising: (1) a polymeric chain comprising one or more polymer segments, at least one polymer segment of which consists of units of at least one fluorine-containing ethylenically unsaturated compound having 2 to 8 carbon atoms, or units of said fluorine-containing ethylenically unsaturated compound and at least one other monomer selected from the group consisting a fluorine-free ethylenically unsaturated compound having 2 to 4 carbon atoms and a fluorine-containing diene having 4 to 8 carbon atoms, (2) at least one bromine atom liberated from a brominated compound of the formula: RBr.sub.x (wherein R is a saturated hydrocarbon residue and x is a number corresponding to the bonding valency of the residue R) in an amount of 0.

Abstract: A catalyst system and process for the selective hydrogenation of aliphatic unsaturation in copolymers containing aromatic groups for example styrene-butadiene copolyers, the catalyst system comprising palladium supported on non-porous carbon black poisoned by a Lewis base containing nitrogen, phosphorus or sulphur moiety.

Abstract: A heat-curable polyurethane composition, comprising:(a) a secondary or tertiary aliphatic diisocyanate;(b) a hydroxyl compound; and(c) a curingly effective amount of a catalyst selected from the group consisting of magnesium acetylacetonate, nickel acetylacetonate, magnesium stearate, cadmium stearate, and organic acid salts of 1,8-diazabicyclo [5.4.0]undec-7-ene.

Abstract: The invention relates to a self-crosslinking heatcurable binder, in particular for electropaints, which is based on an organic synthetic resin which contains primary and/or secondary and, if desired, also tertiary amino groups and esterified carboxyl groups and is water-dilutable due to partial or complete neutralization with acids. The esterified carboxyl groups are activated in the alcohol component by a substituent which induces a negative inductive effect.

Abstract: A polycarboxylic acid alkyl or aryl ester corresponding to the formula ##STR1## is reacted with a dialkanolamine corresponding to the formulaHN--A--OH).sub.2at a temperature from 50.degree. to 200.degree. C. The alcohol ROH formed during this reaction is removed from the reaction mixture and the product recovered corresponds to the formula ##STR2## in which the radicals n, X, A and R are as defined herein. The thus-produced poly-N,N-hydroxyalkylamides are particularly useful as cell-opening materials in the production of elastic polyurethane foams.

Abstract: Silicone foam suppressant compositions are disclosed consisting essentially of a low viscosity polydimethylsiloxane and a high viscosity polydimethylsiloxane, a certain siloxane resin, and amorphous silica. These foam suppressant compositions can be used to suppress foam in both aqueous and hydrocarbon liquids. Advantageously, these foam suppressant compositions employ less of the resin and less amorphous silica than are normally found in silicone foam suppressants.

Abstract: Disclosed is a method for forming pre-froth plastics foam which comprises the steps of mixing the plastics components with a volatile liquid under pressure, causing the mixture to flow to a point of use, and maintaining a series of controlled pressure drops by means of present automatic valves or by passive means such as orifice plates. Typical foams are polyurethane and phenolic.

Abstract: The thermoplastic polyurethane resin having a molecular weight larger than about 5,000 is obtainable by the polyaddition of a long chain diol (A) having a molecular weight ranging from about 500 to 3,000, an organic diisocyanate (C) and a short chain triol (D) having a molecular weight lower than about 500 and specified structures and, as desired, a short chain diol (B) having a molecular weight ranging from about 50 to 500, in specified ratios.The thermoplastic polyurethane resin provides particularly enhanced heat resistance and solvent resistance with improved dispersibility of a pigment or the like and other resins and favorable compatibility with a solvent or the like.

Abstract: Compounds having both s-triazine units and epoxide groups present are prepared by reacting an epoxide containing an isocyanate-reactive group with a triisocyanate corresponding to the formula: ##STR1## in which X is as defined herein. These reactants are used in quantities such that the equivalent ratio of isocyanate groups to isocyanate-reactive groups is maintained at less than or equal to 1 to 1. The compounds thus produced are particularly useful as reactive cross-linkers in the production of polyurethanes and polyepoxides.
