    Abstract: The invention relates to methods of preparing sintered shapes (shaped articles) comprising the steps of forming a green body from a mixture comprising (A) a major amount of at least one inorganic powder with (B) at least one reaction product of an amine other than an alkanolamine with a hydrocarbyl-substituted carboxylic acylating agent or alkylalkyleneglycolacetic acylating agent; provided the reaction product is other than an alkylene oxide treated fatty monocarboxylic amide and provided that when the hydrocarbyl-substituted carboxylic acylating agent is a nonaromatic acylating agent, then the hydrocarbyl group is other than hydrocarbyl groups having an average of about 55 to about 110 carbon atoms; and sintering the green body. Sintered shapes obtainable from the methods of the present invention have relatively high fired densities and small uniform grain sizes and low porosity.

    Abstract: The invention relates to a process for preparing sintered shapes, comprising the steps of: (1) forming a green body from a mixture comprising a major amount of at least one inorganic powder; and one or more additives selected from the group consisting of: (A) at least one reaction product of a hydroxy compound with a carboxylic acylating agent; (B) at least one Mannich reaction product; (C) at least one hydrocarbyl-substituted amine; (D) at least one aminophenol; (E) at least one reaction product of a nitrophenol and amino compound; (F) at least one basic nitrogen-containing polymer; (G) at least one carboxylic acylating agent; (H) at least one aromatic acid or derivative thereof; (I) at least one aromatic oxime; and (J) at least one overbased or gelled overbased metal salt of an acidic organic compound provided that when the carboxylic acylating agent is a hydrocarbyl-substituted carboxylic acylating agent and the hydrocarbyl group contains less than an average of 40 carbon atoms, then the carboxylic acylating agent is a polycarboxylic acylating agent; and (2) sintering the green body. Sintered shapes made from the compositions of the present invention have relatively high fired densities and grain sizes; and relatively low pore volume. (

    Abstract: 2586B Title: METHODS OF PREPARING SINTERED SHAPES AND MethodS USED THEREIN of the invention The invention relates to a method of preparing sintered shapes, comprising the steps of forming a green body from a mixture comprising (A) a major amount of at least one inorganic powder with (B) at least one reaction product of an amine other than an alkanolamine with a hydrocarbyl-substituted carboxylic acylating agent or alkylalkyleneglycolacetic acylating agent; provided the reaction product is other than an alkylene oxide treated fatty monocarboxylic amide and provided that when the hydrocarbyl-substituted carboxylic acylating agent is a nonaromatic acylating agent, then the hydrocarbyl group is other than hydrocarbyl groups having an average of about 55 to about 110 carbon atoms; and sintering the body. Sintered shapes made from the methods of the present invention have relatively high fired densities and small uniform grain sizes; and low porosity. The reaction products of the present invention help disperse the inorganic powder. These reaction products improve deagglomeration of the inorganic powder and help prevent reagglomeration of the powder.

    Abstract: COMPOSICIONES QUE CONTIENEN ELASTOMEROS Y COMPLEJOS METALICOS NO CARBONATADOS. UNA COMPOSICION ADECUADA PAR RECUBRIR OBJETOS METALICOS PARA PROTEGERLOS DE LA CORROSION. LA COMPOSICION COMPRENDE: (A) UN ELASTOMERO; Y (B) AL MENOS UN COMPLEJO METALICO HIDRATADO NO CARBONADO DE: (B-1) AL MENOS UN REACTIVO QUE CONTIENE METAL; Y (B-2) AL MENOS UN REACTIVO ACIDO ORGANICO O UN ESTER O SAL DE METAL ALCALINO O ALCALINO TERREO DEL MISMO, DONDE (B-1) ESTA EN EXCESO ESTEQUIOMETRICO RESPECTO AL REACTIVO ACIDO ORGANICO O ESTER O SAL DE METAL ALCALINO O ALCALINO TERREO DEL MISMO, Y PUEDE CONTENER TAMBIEN OTROS COMPONENTES TALES COMO CERAS, ANTIOXIDANTES, PROTECTORES AUXILIARES CONTRA LA CORROSION, ETC. LAS COMPOSICIONES, CUANDO HAN SIDO APLICADAS A UN OBJETO METALICO, NO SE QUITAN NI DAÑAN FACILMENTE CUANDO SE MANEJAN LOS OBJETOS RECUBIERTOS, RESISTIENDO LOS DAÑOS POR IMPACTO Y/O ABRASION.
