    Abstract: The invention relates to a method of preparing sintered shapes, comprising the steps of: (1) forming a green body from a mixture comprising (A) at least one inorganic powder with (B) at least one polymer derived from (a) at least two sulfo monomers or (b) a combination of (i) a sulfo monomer with (ii) at least one monomer selected from acrylic compounds, acrylonitriles, vinyl lactams and vinyl pyrrolidones and maleic acids, anhydrides or salts, provided the mixture is substantially free of polysaccharide;and (2) sintering the green body. Inorganic shapes made from the compositions of the present invention have relatively high fired densities; small uniform grain sizes; and relatively low porosity.

    Abstract: A process for the preparation of a purified monomer is disclosed which comprises the steps of reacting an impure monomerwherein R1 and R2 are independently hydrogen or alkyl groups containing from 1 to about 6 carbon atoms, with(B) a substantially aqueous solution of an oxide or hydroxide of the structure MO or MOH wherein M is a Group IA or Group IIA metal, or an amine of the structure NR3R4R5 wherein R3, R4 and R5 are independently hydrogen or alkyl, alkanol or alkoxy groups containing from 1 to about 12 carbon atoms,wherein the molar ratio of (A):(B) is from about 1:1-2 for Group IA metals, 2:1-2 for Group IIA metals or ratio of moles of (A) to nitrogens of (B) is from about 1:1-2 nitrogens to form a salt, wherein in order to prevent polymerization of (A), the purified monomer or both or prevent undesired side reactions, the reaction of (A) and (B) occurs at a temperature of between about -20 to 75° C. and at a pH between about 7 to about 12.5, and recovering a purified salt by crystallization in the presence of an oxygen bearing gas stream by subjecting the aqueous solution to changes in temperature and/or pressure and/or concentration.

    Abstract: The invention relates to (1) 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 a alkanolamine with a hydrocarbyl-substituted carboxylic acylating agent provided that when the hydrocarbyl group of the acylating agent contains less than 40 carbon atoms then the carboxylic acylating agent is a polycarboxylic acylating agent; and (2) sintering the green body. Sintered shapes made from the methods of the present invention have relatively high fired densities and small uniform grain sizes and low porosity.
