20100249001 | AMINE-TERMINATED TELECHELIC POLYMERS AND PRECURSORS THERETO AND METHODS FOR THEIR PREPARATION - Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with a functionalized N-substituted pyrrole to thereby introduce the functionalized N-substituted pyrrole at the terminal reactive polymer chain end(s). A method is also disclosed whereby the N-substituent may be derivatized to a basic amine containing functional group. Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is substituted at the 2 and 3 position of the N-substituted pyrrole. | 09-30-2010 |
20110256085 | RHEOLOGY MODIFIER COMPOSITIONS AND METHODS OF USE - A composition for enhancing fluid viscosity including a mixture of at least one cationic or cationizable polymer and at least one anionic or anionizable (hydrolysable) polymer. The composition has a zeta potential at 25° C. in the range of 0.5 to 100 mV or −0.5 to −100 mV, typically 1 to 60 mV or −1 to −60 mV, or is a precursor convertible at a temperature of 100 to 250° C. to the composition having a zeta potential at 25° C. of 0.5 to 100 mV or −0.5 to −100 mV, typically 1 to 60 mV or −1 to −60 mV. Typically the compositions exhibit salt tolerance and interaction of both polymers at very high temperatures (>300° F.) such that the system exhibits an increase of viscosity at extreme temperatures. The compositions are useful for hydraulic fracturing, enhanced oil recovery, subterranean acidization, personal care as well as home and industrial cleaners. | 10-20-2011 |
