POLYBENZOXAZINE ASPHALTENE INHIBITORS

A method of stabilizing asphaltenes in a petroleum hydrocarbon fluid is disclosed. The method includes contacting the petroleum hydrocarbon fluid with a polybenzoxazine comprising repeating structural units of Formula (I):wherein R1 is hydrogen, a C1-30 alkyl, a C3-30 cycloalkyl, a C6-30 aryl, a C7-...

Zusammenfassung:	A method of stabilizing asphaltenes in a petroleum hydrocarbon fluid is disclosed. The method includes contacting the petroleum hydrocarbon fluid with a polybenzoxazine comprising repeating structural units of Formula (I):wherein R1 is hydrogen, a C1-30 alkyl, a C3-30 cycloalkyl, a C6-30 aryl, a C7-30 alkylarylene, a C7-30 arylalkyl, a C5-30 heteroaryl, or a C3-30 heterocycloalkyl; and R2 is a C1-30 alkyl, a C3-30 cycloalkyl, a C6-30 aryl, a C7-30 alkylarylene, a C7-30 arylalkyl, a C5-30 heteroaryl, or a C3-30 heterocycloalkyl.
