Antiplasticizer For High Impact Polystyrene

View page
US Patent:
42357608, Nov 25, 1980
Filed:
May 24, 1979
Appl. No.:
6/042386
Inventors:
Christopher W. Uzelmeier - Houston TX
Paul M. Coffman - Houston TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C08L 9106
US Classification:
260 285B
Abstract:
High impact polystyrene compositions having improved melt flow properties along with good heat resistance is obtained by incorporating about 0. 5 to 10 percent by weight of an oxidized polyethylene material having a molecular weight of from about 500 to about 5,000 and an acid number of between about 5 and about 50.

Process For Preparing A Bisphenol

View page
US Patent:
50084704, Apr 16, 1991
Filed:
Nov 30, 1989
Appl. No.:
7/444580
Inventors:
Joseph B. Powell - Houston TX
Christopher W. Uzelmeier - Houston TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C07C 3720
C07C 3916
US Classification:
568727
Abstract:
The present disclosure is directed to acid scavenging in the acid-catalyzed preparation of a bisphenol by condensation of a phenolic compound and a carbonyl compound. During the preparation, strong acids leach from the acidic ion exchange resin catalyst into the reaction effluent. These acids can be scavenged effectively and without contamination by an inorganic oxide before purification of the product. The acid scavenging improves the product quality and yield by reducing acid catalyzed cracking of bisphenols during purification and finishing steps.

Low Viscosity Vinyl Ester Resins

View page
US Patent:
43574564, Nov 2, 1982
Filed:
Aug 28, 1981
Appl. No.:
6/297293
Inventors:
John A. Lopez - Houston TX
Christopher W. Uzelmeier - Houston TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C08G 5916
US Classification:
5281115
Abstract:
Vinyl esters exhibiting reduced viscosity are prepared by esterifying at least 90% of the pendant hydroxyl groups of a vinyl ester prepared by reacting an epoxy resin with an ethylenically unsaturated carboxylic acid with a fatty acid or rosin acid.

Process For Preparing A Bisphenol

US Patent:
51050269, Apr 14, 1992
Filed:
Nov 15, 1990
Appl. No.:
7/613433
Inventors:
Joseph B. Powell - Houston TX
Christopher W. Uzelmeier - Houston TX
Assignee:
Shell Oil Company - Houston TX
International Classification:
C07C 3720
C07C 3916
US Classification:
568727
Abstract:
The present disclosure is directed to improving purity of a bisphenol product in a bisphenol by-product isomerization process wherein isomers of bisphenol are isomerized to the desired bisphenol product. During the isomerization, acidic resin fines elute from the acidic ion exchange resin catalyst into the reaction effluent. These resin fines can be filtered effectively and without contamination by a bed of solid particles such as alumina or carbon. The removal of resin fines improves the product quality and yield by eliminating resin particulates and reducing acid catalyzed cracking of bisphenols during purification and finishing steps.
