Abstract: A method of controlling the rheology of a sealing glass paste which comprises incorporating a fine inorganic powder in the paste as a mill addition to impart a steep rheology curve to the paste so that the paste resists flow while at rest, but flows readily when shear stress is applied, the amount of inorganic powder incorporated being not over about 10% by weight.

Abstract: A method of producing a formable mixture involves combining a powder material, and a plurality of gel-forming polymers, wherein at least one gel-forming polymer is a proton donor, and at least one gel forming polymer is a proton acceptor. A method of making a monolithic structure involves producing a formable mixture of powder material which can be ceramic, metal, glass, glass ceramic, molecular sieve and combinations thereof, a plurality of gel-forming polymers as described above, extruding the mixture to form a green monolithic structure, and drying and firing the green structure.

Abstract: Reduced gloss polycarbonate graft polymer blends are provided by a process which involves compounding styrene-acrylonitrile copolymer in the presence of an electrophilic reagent and preferably an acid to form gels, and then compounding the resultant gels with polycarbonate, a styrene-acrylonitrile copolymer and ABS graft polymer to form reduced gloss PC/ABS/SAN composition. The process limits side reactions during gel formation by preparing the gels first and then compounding the gels with the other resin materials. The blends are useful as molding resins and the gelled acrylonitrile polymer is useful as a gloss reducing additive.

Abstract: A thermoplastic composition is provided comprising an acrylonitrile-butadiene-styrene graft copolymer, polycarbonate and an epoxy functional silicone. The compositions exhibit reduced gloss and enhanced low temperature impact strengths and are useful as molding resins.

Abstract: There are disclosed thermoplastic resin compositions with improved impact strength and other physical properties, specifically compatibilized compositions comprising polyphenylene ethers and thermoplastic polyesters, with the compatibilization being effected through the use of polystyrene-polycarbonate copolymer.

Abstract: The invention relates to polymer compositions comprising an aromatic polycarbonate, an aromatic polycarbonate with acid or ester functionality, a styrene based polymer and a styrene polymer with oxazoline groups.The polymer composition of the invention is suitable for molding objects with a mat surface.

Abstract: Peroxy-terminated polycarbonates are prepared by the reaction of an aromatic dihydroxy compound, preferably a bisphenol, with phosgene in one or two steps, in the presence of a peroxy ester such as the mono-t-butyl perester of maleic acid. The peroxy-terminated polycarbonates may be employed to initiate vinyl polymerization of ethylenically unsaturated monomers or to react with polymers containing ethylenically unsaturated groups, to form copolymers which are useful as compatibilizers for blends of polycarbonates with said polymers.

Abstract: Alkylperoxyformate-terminated polycarbonates are prepared by the reaction of an aromatic dihydroxy compound, preferably a bisphenol, with phosgene in one or two steps, in the presence of an alkyl hydroperoxide such as t-butyl or 2-phenyl-2-propyl hydroperoxide. The alkylperoxyformate-terminated polycarbonates may be converted to hydroxy-terminated polycarbonates by heating in the melt.
