Abstract: A thixotropic, smooth-flowing liquid, bulk-water-free dentifrice gel/paste that contains a stable mixture of at least one of amylopectin containing discrete solid particles and modified amylopectin containing discrete solid particles, uniformly suspended in and wetted by an inert essentially anhydrous organic hydroxylated liquid matrix material, and which dentifrice gel/paste is characterized by a high surface sheen. Preferably, the modified homopolysaccharide discrete particles contain esterified amylopectin and/or esterified amylose. The dentifrice gel/paste can be used as a toothpaste, a bleaching gel and a brushing gel.

Abstract: A transfer-pad printing composition comprising either a latex or solution coating composition comprising a coating vehicle and a monomeric or polymeric hydroxylated and/or carboxylated surface active wetting agent that is coating compatible with the pad surface such that the coating composition, provided in the shape of a pattern, is precisely imprinted on its surface and the pad can precisely transfer the design to another surface that is receptive to the coating. The process of transfer-pad printing with the composition. Also, articles made by such transfer printing.

Abstract: This invention relates to a process for making amines by condensing an amino compound in the presence of a condensation catalyst and a condensation catalyst promoter, wherein said condensation catalyst promoter is present in an amount sufficient to promote the condensation catalyst. This invention also relates to an alkyleneamines producers composition rich in triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and pentaethylenehexamine (PEHA).

Abstract: Process of making amines by inter alia the (i) intramolecular condensation of an amino compound to an amine having a lower molecular weight or (ii) the intermolecular condensation of an amino compound with one or more of another amino compound or a compound containing an alcoholic hydroxyl group using a Group IVB metal oxide condensation catalyst. The preferred process involves the manufacture of alkyleneamines, most desirably polyalkylenepolyamines, by such condensation reactions utilizing catalysts containing titanium oxide, zirconium oxide or mixtures of them.

Abstract: This invention relates to vicinal di(hetero)alkylene organometalate compounds comprising one or more metal oxides in association with an alkanolamine, an alkyleneamine, an alkylene glycol or mixtures thereof. This invention also relates to an alkyleneamines producers composition rich in triethylenetetramine (TETA), tetraethylenepentamine (TEPA) and pentaethylenehexamine (PEHA), and to processes for the preparation thereof using the vicinal di(hetero)alkylene organometalates.

Abstract: The invention relates to tough, crystalline polyetherketones, processes for making them and monomers used in their manufacture. The polyetherketones are derived from monomers which provide the repeating polymer unit-(-O-Ph-CO-Ph-CO-Ph-).gtoreq.2- in the polymer chain.The polyetherketones are the etherification reaction product ofX-Ph-CO-Ph-[ -CO-Ph-].sub.1 -[-Ph-CO-Ph-(-CO-Ph-).sub.o -].sub.m -Xwherein X is a halogen such as fluorine and chlorine, l, m and o are individually 0 or 1, with a bisphenol of the formulaHO-Ph-(-Y-Ph-).sub.p -OH,wherein p is 0, 1 or 2, -Y- is -CO- or -O- in either occurence, and an aromatic hydroxy halide of the formulaHO-Ph-CO-Ph-CO-Ph-X,wherein X is as described above, and wherein -Ph- is 1,4-phenylene, said polyetherketone having an ether to ketone molar ration of less than 2/1 and greater than 1/2, and an inherent viscosity of at least 0.6.

Abstract: Described herein are molding compositions comprising a blend of (a) a polyarylate derived from a dihydric phenol and a mixture of isophthalic acid and terephthalic acid, of which more than about 65 mole percent is terephthalic acid, (b) a polyarylate derived from a dihydric phenol and a mixture of terephthalic acid and isophthalic acid, of which more than about 70 mole percent is isophthalic acid, and (c) at least one thermoplastic polymer compatible therewith. An article molded from these compositions has a good balance of mechanical properties and improved environmental stress crack resistance.
