Abstract: A composite pigment product useful as a paper filler pigment comprises a mineral nucleus coated with a substantially continuous substantially uniform coating of an active paper pigment. The active paper pigment coating is preferably formed in situ under alkaline conditions.

Abstract: Compositions for producing foamed products which include filler and/or pigment additives and blowing agents which enhance the strength of weld lines which are produced when the compositions are molded. The products produced from the compositions have weld line that demonstrate superior strengths as compared to similar foamed products which do not utilized the particular blowing agents.

Abstract: An improved method for the production of synthetic hydrotalcites having high purity (99+%) and small particle size (<2 microns) is disclosed. This method used inexpensive and available reactants and is suitable for commercial scale production. A source of magnesium, such as magnesium hydroxide; a source of aluminum from a mixture of alumina trihydrate and an alkali metal aluminate; and a source of carbonate, such as sodium bicarbonate, are reacted under hydrothermal conditions at a temperature of between 160.degree.-200.degree. C. to produce synthetic hydrotalcite.

Abstract: A stabilized powdered endothermic blowing agent which is a mixture of a polycarboxylic acid and an inorganic carbonate, the polycarboxylic acid and inorganic carbonate each having been surface treated with a component which prevents water from being absorbed thereby The blowing agent is incorporated into a polymeric concentrate used for producing foamed products.

Abstract: A family of novel and unique synthetic alkali metal alumino-silicates (SAMS) are produced by the hydrothermal reaction between kaolin and alkali metal silicates. The integrated composition of the SAMS products is a unique entity having an overall composition ofxM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 :zH.sub.2 Owhere x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is the alkali metal, y is the number of moles of SiO.sub.2 in the unique SAMS compositions and is an integer greater than 2.0, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The unique SAMS compositions are structured materials in which the structure can be controlled, and are therefore useful as functional fillers, as TiO.sub.2 extenders, as silica extenders or as reinforcing agents for paper, paint, rubber, plastics and specialty products.
