43084028, Dec 29, 1981

Filed:

Nov 20, 1979

Appl. No.:

6/096122

Inventors:

Charles L. Edwards - Houston TX
Andrea Sanders - Houston TX
Lynn H. Slaugh - Houston TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

C07C 4311

US Classification:

568618

Abstract:

A terminal --CH. sub. 2 OH moiety is selectively cleaved from an alkoxyalkanol at elevated temperatures, in the optional presence of water, over a catalytically effective amount of heterogeneous nickel.

US Patent:

Filed:

Jul 6, 1981

Appl. No.:

6/280737

Inventors:

Andrea Sanders - Katy TX
Leo Kim - Modesto CA

Assignee:

Shell Oil Company - Houston TX

International Classification:

C07C 51235

US Classification:

562538

Abstract:

Alkoxyalkanols are oxidized to the corresponding alkoxyalkanoic acids by contacting the alkanols with oxygen in the presence of a catalyst comprising platinum supported on a macroreticular cross-linked polystyrene/divinylbenzene resin. Enhanced rates are obtained.

Filed:

Jun 25, 1990

Appl. No.:

7/542687

Inventors:

Andrea Sanders - Katy TX
Glenn R. Himes - Houston TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

C09J15302
C08L 5302

US Classification:

156334

Abstract:

An adhesive composition comprising a plurality of selectively hydrogenated block copolymers, each of said block copolymers comprising at least one polymeric block containing predominantly monoalkenyl aromatic hydrocarbon monomer units and at least one polymeric block containing predominantly conjugated diolefin monomer units, at least one of which block copolymers is carboxylated and at least one of which block copolymers is not carboxylated and laminated structures comprising a plurality of polymeric layers tied together with said adhesive composition. The adhesive composition contains a relatively minor amount of carboxyl groups, on average, per polymer chain in the composition and is particularly useful in the preparation of laminated structures via coextrusion or similar processes, wherein the various layers are brought together in the molten phase while in motion, when one or more layers in the laminated structure comprises a polar group reactive with the carboxyl groups. Laminated structures prepared with the adhesive composition can be prepared and processed at higher temperatures than similar laminated structures heretofore known.

Appl. No.:

7/138780

Inventors:

Glenn R. Himes - Houston TX
Andrea Sanders - Katy TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

C08L 5302

US Classification:

525 89

Abstract:

A thermoplastic blend with the ability to absorb less than 40% of an oil, and having a superior tensile strength comprises about 80 to about 20 phr of an elastomeric block copolymer having the general configuration A-B-A, wherein the B block is a butadiene hydrocarbon block consisting of about 35 to about 55 mole percent of condensed butadiene units in the 1,2 configuration, and about 20 to about 80 phr of a block copolymer having the general configuration A-B-A, wherein the B block is a hydrogenated butadiene hydrocarbon block consisting of about 18 to about 34 mole percent of condensed butadiene units in the 1,2 configuration.

Appl. No.:

6/484754

Inventors:

Connie L. Merrill - Houston TX
Andrea Sanders - Houston TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

G01T 1161

US Classification:

250303

Abstract:

A reliable method for testing the performance of detergent compositions, particularly from the standpoint of the redeposition of soils on fabrics during the laundry wash cycle, which comprises subjecting a clean control fabric swatch to multiple washings, each washing conducted in a solution of the detergent composition and in the presence of one or more pre-soiled fabric swatches, and then analyzing the control swatch for soil content, for example, by light reflectance or radiotracer methods.
