    Abstract: PROBLEM TO BE SOLVED: To obtain a copolymer suitable for a variety of applications such as resins and films and a solid mixture useful as a coagulant, a dispersant, an adhesive and a thickener by mixing an acrylamide-alkanesulfonic acid and a specific basic compound. SOLUTION: An acrylamide-alkanesulfonic acid usually in a solid form (for example, 2 acrylamide-2-methylpropanesulfonic acid) and a basic compound which is reactive with said acrylamide-alkanesulfonic acid in a solution to form the salt (sodium carbonate or the like containing an anion forming a volatile compound on acidification) are mixed at an equivalent ratio of about 1/0.8-1/2 through dry mixing, inline static mixing or in an inactive liquid medium (a hydrocarbon, for example, hexane or benzene or ether), then said medium is removed.

    Abstract: Dispersant salt compositions are made by reacting phosphorus-free carboxylic solubilizers with sulfonic acid-free organic acids or mineral acids. The carboxylic solubilizer can be made by the reaction of a polycarboxylic acid acylating agent having at least one hydrocarbon-based substituent of at least 8 to 500 carbon atoms with at least one poly(alkyleneamine). The dispersant salts have good thermal stability when mixed with a surfactant or a hydrophilic organic solvent. The compositions can be used with aqueous solutions to disperse various fillers including carbon black, as well as to solubilize various fluids.

    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.
