International Classification:

C08F 464

US Classification:

526116, 526129, 526160, 526161, 526171, 5263485, 5263486, 526907, 526903, 526943, 526352, 502104, 502117, 502152

Abstract:

The invention provides for polymerization catalyst compositions, and for methods for introducing the catalyst compositions into a polymerization reactor. More particularly, the method combines a catalyst component containing slurry and a catalyst component containing solution to form the completed catalyst composition for introduction into the polymerization reactor. The invention is also directed to methods of preparing the catalyst component slurry, the catalyst component solution and the catalyst compositions, to methods of controlling the properties of polymer products utilizing the catalyst compositions, and to polymers produced therefrom.

International Classification:

B08B 304
C23G 506

US Classification:

134 40

Abstract:

A method for removing rosin soldering flux with aqueous cleaning compositions. The aqueous cleaning compositions can be employed for household use or for cleaning electronic circuit assemblies. The aqueous cleaning compositions contain an alkaline salt, an alkali metal silicate to boost detersive action or to provide corrosion protection to the substrates which are cleaned and an anionic polymer of a high molecular weight polyacrylic acid which stabilizes the alkali metal silicate to prevent precipitation of the silicate from solution.

International Classification:

C11D 310
C11D 337

US Classification:

25217424

Abstract:

The present invention is directed to aqueous cleaning concentrates such as for cleaning electronic circuit assemblies comprising 15-30 wt. % of a composition containing alkaline salt, an alkali metal silicate to boost detersive action or to provide corrosion protection to the substrates which are cleaned, an anionic polymer comprising a high molecular weight polyacrylic acid which stabilizes the alkali metal silicate to prevent precipitation of the silicate from solution, surfactants, and a hydrotrope to maintain the surfactants in solution and the balance water.

Assignee:

Church & Dwight Co., Inc. - Princeton NJ

International Classification:

B24B 100

US Classification:

451 39

Abstract:

An improved slurry blasting process is disclosed wherein a liquid carrier medium such as water contains a dispersed water-soluble particulate abrasive to enhance blast cleaning efficiency and wherein the liquid carrier comprises a saturated solution such as the dissolved particulate abrasive so as to minimize the dissolution of the particulate abrasive therein. Slurry blasting at relatively low pressures below 500 psi and at room temperature provides effective and cost efficient cleaning of substrates. The slurry can be recovered and continuously reused. A recrystallization agent can be added to the slurry to increase abrasive particulate growth in the saturated solution.

US Classification:

451 36

Abstract:

A method of cleaning a solid surface which is particularly effective for a surface having a complicated structure including slots and holes comprises immersing the solid surface in a cleaning slurry comprising a cleaning liquid and abrasive particles which are soluble in the cleaning liquid, the cleaning liquid comprising a saturated solution so as to greatly reduce the dissolution of the abrasive particles in the cleaning liquid.
