US Patent:

46277358, Dec 9, 1986
Filed:

Feb 7, 1985
Appl. No.:

6/699335
Inventors:

Philip M. Rose - Naperville IL
Yoon S. Song - Lisle IL
Assignee:

Standard Oil Company (Indiana) - Chicago IL
International Classification:

B01F 700
US Classification:

366329
Abstract:

The double reverse helix agitator with an internal conveying screw is used in a gas phase olefin polymerization reactor having at least one polymerization section and has helical flights defined by helical blades which are mounted to a shaft, which extend in opposite axial directions and which have approximately the same radius from the axis of rotation of the agitator. The shaft has a spiral screw thread thereon for conveying polymer particles axially by the agitator through a reactor vessel.

US Patent:

46633928, May 5, 1987
Filed:

May 16, 1986
Appl. No.:

6/864067
Inventors:

Yoon S. Song - Lisle IL
Henry A. McCandless - Godfrey IL
Assignee:

Amoco Corporation - Chicago IL
International Classification:

C08F 834
C08L 2330
C08L 2332
C08L 2336
US Classification:

525155

US Patent:

49632779, Oct 16, 1990
Filed:

Oct 20, 1988
Appl. No.:

7/260254
Inventors:

David J. Fenoglio - Wheaton IL
Yoon S. Song - Naperville IL
Robert J. Basalay - Naperville IL
Assignee:

Amoco Corporation - Chicago IL
International Classification:

C10M10558
US Classification:

252 515A
Abstract:

A method is described for improving the viscosity storage stability of a Mannich base condensation product of an oxidized polyolefin, formaldehyde, and an amine. This method involves contacting such Mannich base condensation product with a lower alkyl peroxide, a lower alkyl hydroperoxide or an aryl(lower)alkyl hydroperoxide at a temperature of about 250. degree. F. to about 400. degree. F. for a time period sufficient to provide an oxidized product.

Filed:

Mar 30, 1987
Appl. No.:

7/031355
Inventors:

Yoon S. Song - Lisle IL
Robert J. Basalay - Naperville IL
Assignee:

Amoco Corporation - Chicago IL
International Classification:

C10M15916
US Classification:

252 515A
Abstract:

Improved dispersant and VI-improving Mannich composition having reduced susceptibility to viscosity increase during storage, which composition comprises a physical blend prepared by admixing a phenolic compound with a Mannich condensation product obtained from the Mannich reaction of an oxidized polymer, an amine and a formaldehyde-yielding reagent.
