Filed:

Jan 31, 2006

Appl. No.:

11/343796

Inventors:

Steluta Butuc - The Woodlands TX, US
David Morrison - The Woodlands TX, US
Julie Thompson - The Woodlands TX, US

International Classification:

C08J 3/02

US Classification:

516098000

Abstract:

This invention is a hydrocarbon gel concentrate containing a high polymer load and a polar compound. The method of the present invention allows for increasing polymer load of a mineral oil gel through the addition of a polar compound as a processing aid during gel formation such that the viscosity of the resulting hydrocarbon gel concentrate is mixable at processing temperature, thereby allowing dilution of the hydrocarbon gel concentrate with additional hydrocarbon oil.
