Thixotropic Anhydrous Shear Thinning Peroxide Dispersions
US Patent:
2011029, Dec 1, 2011
Filed:
Feb 3, 2010
Appl. No.:
13/147457
Inventors:
Joseph M. Gravelle - Spring City PA, US
Thomas H. Kozel - Pottstown PA, US
Thomas H. Kozel - Pottstown PA, US
Assignee:
Arkema Inc. - King of Prussia PA
International Classification:
C09K 3/00
US Classification:
25218214
Abstract:
Provided are dispersions which comprise more than about up to 55 percent by weight or more of an organic peroxide which is normally solid in an anhydrous liquid phase such as dibutyl maleate or dioctyl adipate, with about 5% by weight or more fumed silica to provide a thixotropic, storage stable organic peroxide paste. Addition of about 5 weight % or more of fumed silica was found to result in the formation of a shear thinning anhydrous dispersion of organic peroxide which was storage stable.
Polymerization Controllers For Organic Peroxide Initiator Cured Composites
US Patent:
2011025, Oct 13, 2011
Filed:
Nov 24, 2009
Appl. No.:
13/140497
Inventors:
Thomas H. Kozel - Pottstown PA, US
Michael O. Wells - Sinking Spring PA, US
Michael O. Wells - Sinking Spring PA, US
Assignee:
Arkema Inc. - King of Prussia PA
International Classification:
B32B 1/08, C08F 36/04, C08F 20/10, C09K 3/00, C08F 18/04
US Classification:
428 369, 25218214, 526193
Abstract:
The use of nitroxides to control free radical cured resin systems used in the production of thermosetting materials such as in vacuum infusion, resin transfer molding and cured in place piping systems is disclosed. The invention could also be employed in other resin systems where control of kinetics would be desirable such as in adhesive formulations, in solid surface composites, and certain types of polyester casting resins.

Arkema Inc. - Philadelphia PA
International Classification:
C08K 5/092, C09K 3/00
US Classification:
524293, 25218212
Abstract:
Provided are dispersions which comprise more than about (40) percent by weight of an organic peroxide which is normally solid, an effective dispersing amount of a pharmaceutically acceptable dispersing agent and water. The water and about (40) percent or more peroxide forms a paste. Addition of the dispersing agent/surfactant to a non-flowing organic paste resulted in the formation of a shear thinning aqueous dispersion. The aqueous dispersions can also contain optional components such as thickening agents and anionic emulsifiers.
