10/242209
Inventors:
Zaida Diaz - Houston TX
Grant W. Haddix - Katy TX
Grant W. Haddix - Katy TX
Assignee:
KRATON Polymers U.S. LLC - Houston TX
International Classification:
C08F 446
US Classification:
526173, 526335, 502 31, 502 85, 502514

Removing silicon species from hydrocarbon solvents such as cyclohexane by flowing the hydrocarbon solvent through a selective adsorbent selected from the group consisting of aluminas, silicon-aluminas, ion exchange resins, zeolite Y, and combinations thereof.
Method For Synthesis Of A Dilithium Diisopropenylbenzene-Based Diinitiator
US Patent:
6217798, Apr 17, 2001
Filed:

Assignee:
Shell Oil Company - Houston TX
International Classification:
C07F 102
US Classification:
260665R
Abstract:
This invention is a process for making a difunctional lithium initiator which comprises reacting a secondary or tertiary lithium alkyl with a diisopropenylbenzene compound in the presence of diethyl ether at a temperature of 25 to 50. degree. C. wherein the molar ratio of the diethyl ether to the lithium alkyl is from above 0. 1:1 to 2:1 and the diisopropenylbenzene compound and the diethyl ether are first mixed together and then added to the lithium alkyl. The molar ratio of the diisopropenylbenzene compound to the lithium alkyl should be as close to 0. 5:1 as possible. An excess of lithium alkyl may be used if a product containing both diinitiator and monoinitiator is preferred. It is preferred that the molar ratio of diethyl ether to lithium alkyl be as close to 1:1 as possible.

Assignee:
Kraton Polymers U.S. LLC - Houston TX
International Classification:
C08F 25/02
US Classification:
525242
Abstract:
Disclosed is an anionic diinitiator prepared using a diisopropenyl benzene compound and an organo lithium compound having primary polymerization sites. The anionic diinitiators are prepared by admixing a diisopropenyl benzene compound with diethyl ether, ethylene, an organo lithium compound, and a solvent under reaction conditions sufficient to prepare a diinitiator having primary lithium alkyl reactive sites. The diinitiators are particularly useful in preparing block copolymers.

International Classification:
C08F 3606, C08F 446
US Classification:
526335
Abstract:
The preparation of di- or polyfunctional polymers by anionic polymerization using functionalized initiators having the structure R. sup. 1 R. sup. 2 R. sup. 3 Si--A--B, wherein each R is methyl and A is a hydrocarbon bridging group containing from 1 to 25 carbon atoms, and B is an alkali metal, is improved when polymerization occurs in the presence of a polymerization termination inhibitor which is a metal alkyl which has been added at a concentration to afford a molar ratio of the termination inhibitor to living polymer chain ends of about 0. 1:1 to about 10:1.
