Process For Selective Hydrogenation Of Conjugated Diolefin Polymers

View page
US Patent:
51323729, Jul 21, 1992
Filed:
Sep 9, 1991
Appl. No.:
7/756392
Inventors:
Linda R. Chamberlain - Richmond TX
Carma J. Gibler - Houston TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C08F 804
US Classification:
525338
Abstract:
This is an improved process for the hydrogenation of conjugated diolefin polymers which comprises polymerizing or copolymerizing at least one conjugated diolefin with an organo alkali metal polymerization initiator in a suitable solvent thereby creating a living polymer, terminating the polymerization by the addition of hydrogen and effecting selective hydrogenation of the unsaturated double bonds in the conjugated diolefin units of the terminated polymer by contacting the polymer, in the absence of hydrocarbon lithium and alkoxy lithium compounds, with hydrogen in the presence of at least one bis(cyclopentadienyl)titanium compound. The improvement is the use of methyl benzoate as a promoter in the hydrogenation step.

Color Prevention In Titanium Catalyzed Hydrogenated Diene Polymers

US Patent:
52800598, Jan 18, 1994
Filed:
Apr 16, 1993
Appl. No.:
8/049690
Inventors:
Linda R. Chamberlain - Richmond TX
Carma J. Gibler - Houston TX
Miguel Prado - Sugarland TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C08F 800
US Classification:
524147
Abstract:
The present invention is an improvement upon a process for hydrogenating a diene polymer by contacting the polymer in the presence of hydrogen with a titanium hydrogenation catalyst. The improvement comprises preventing discoloration of the hydrogenated polymer by treating it with water, a peroxide or alcohol in the absence of oxygen and adding a non-phenolic antioxidant to the polymer.

Selective Hydrogenation Of Conjugation Diolefin Polymers With Rare Earth Catalysts

View page
US Patent:
51771551, Jan 5, 1993
Filed:
May 13, 1991
Appl. No.:
7/699028
Inventors:
Linda R. Chamberlain - Richmond TX
Carma J. Gibler - Houston TX
Richard A. Kemp - Stafford TX
Stanley E. Wilson - Houston TX
Thomas F. Brownscombe - Houston TX
Assignee:
Shell Oil Company
International Classification:
C08F 804
US Classification:
525338
Abstract:
This invention provides a catalyst and a process for the hydrogenation of conjugated diolefin polymers which first involves the polymerization or copolymerization of such monomers with an organo alkali metal polymerization initiator in a suitable solvent thereby creating a living polymer. The living polymer can be terminated by the addition of hydrogen. Finally, selective hydrogenation of the unsaturable double bonds in the conjugated diolefin units of the terminated polymer is carried out in the presence of an initiator and at least one rare earth compound of the formula *Cp. sub. MR where *Cp is pentamethylcyclopentadiene, M is a rare earth element and R is alkyl, aryl, aralkyl or hydrogen.

7/863648
Inventors:
Robert C. Bening - Katy TX
James R. Erickson - Katy TX
David J. St. Clair - Houston TX
Carma J. Gibler - Houston TX
Joe J. Flores - Sugarland TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C08F 800
US Classification:
5253328
Abstract:
A process for making polymers of conjugated dienes which contain hydroxyl groups in the diene blocks which comprises (a) making a precursor polymer by polymerizing at least one conjugated diene which leaves 1,2 disubstituted, 1,1 disubstituted, 1,1,2 trisubstituted or tetrasubstituted olefinic unsaturation in the polymer, (b) optionally partially hydrogenating said precursor polymer, (c) epoxidizing said precursor polymer such that epoxy groups form at said substituted sites and the amount of epoxy functionality in the polymer is from 0. 1 to 5 Meq/g polymer, and (d) reacting the epoxidized polymer with an alcohol solution of hydrochloric acid. A diene polymer containing 0. 1 to 10 Meq/g polymer of hydroxyl group and comprised of alcohol units of the formula ##STR1## where R. sub. 1 and R. sub. 2 are hydrogen or alkyl radicals and X and X' are either --OH or --Cl and at least one of them is --OH.
