    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: 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: Modified asphalt compositions are described which comprise (A) asphalt, and (B) a minor effective amount, sufficient to improve the durability of the asphalt in service, of at least one hydrocarbon-soluble acrylate polymer of the formula wherein R1 is a lower alkyl group containing from 1 to about 4 carbon atoms, R2 is a mixture of alkyl groups containing from about 4 to about 20 carbons atoms, and x is an integer providing a weight average molecular weight (Mw) to the acrylate polymer of about 5000 to about 1,000,000. Generally, the modified asphalt compositions will contain from about 0.01 to about 10% by weight, based on the weight of the asphalt, of the acrylate polymer as defined. The modified asphalt compositions of the present invention are useful in roofing and in preparing aggregate-containing asphalt concretes which can be employed as paving compositions.
