The present invention provides an improved process for the production of alumina trihydrate crystals. Through the addition of a hydroxamated polymer at various stages of the process for production of these alumina trihydrate crystals, an upward shift in the particle size distribution of the alumina trihydrate crystals occurs. In one embodiment, the hydroxamated polymer is added to a filtered aqueous solution, which comprises no more than about mg of insoluble solids per liter. In another embodiment, the hydroxamated polymer is added to an aqueous solution comprising insoluble solids after precipitation of alumina trihydrate crystals has commenced. Optionally, alumina trihydrate seed crystals may be added to the aqueous solution to initiate or encourage crystal formation.

The current invention describes organoclay compositions and methods of using them for removing impurities from contaminated liquids. The compositions are formed by contacting an attapulgite, sepiolite, or zeolite clay mineral with an alkylamine base. The method of use involves contacting the organoclay composition with a contaminated liquid, such as oil in water, allowing the organoclay to absorb the contaminants. The organoclay can be in the form of a granular solid for inline filter applications, or it can be a finely divided powder for other applications.

Aqueous suspensions of paints in waste waters can be treated to detackify the paint and facilitate its removal by contacting the paint suspension at a pH of from about 5 to about 14 with a polyarylamine that is produced by reacting an aldehyde with an arylamine in the presence of an acid in an aqueous suspension. The same polyarylamine can also be used for reducing the color content of highly colored liquids. Compositions containing the polyarylamine are also described.

A thermally activated adhesive for coating and holding a multi-end band wire together through a high volume, high speed banding line which comprises a polyolefin in an amount of 2 to 98% by weight based upon the total weight of the adhesive, an acid in an amount of 1 to 20% by weight based upon the total weight of the adhesive and a rubber polymer in an amount of 1 to 20% by weight based upon the total weight of the adhesive. The adhesive activates in a temperature range of between 200 F. to 500 F. and is characterized in that it has a tensile strength of between 1,500 to 10,000 psi as determined by ASTM D638-96 and a peel strength of between 5 to 10 PLI as determined by ASTM D903-93.
