METHOD OF PRODUCING AMORPHOUS SUPERHIGH MOLECULAR WEIGHT POLYOLEFINS DESTINED FOR USE AS FLOW RESISTANCE LOWERING AGENTS Russian patent published in 2006 - IPC C08F10/00 F15D1/06 F17D1/16 F17D1/17 C08F10/14 C08F210/14 C10M143/00

Abstract RU 2277103 C2

FIELD: polymer production.

SUBSTANCE: invention is aiming at production of flow resistance lowering agents containing non-crystalline poly-α-olefin with especially high molecular weight. Method resides in preliminary isomerization of α-olefin monomers including at least one monomer selected from group consisting of 1-hexene, 1-octene, 1-decene, 1-dodecene, and mixtures thereof via bringing α-olefin feed into contact with isomerization Y-type zeolite catalyst system containing at least one catalyst and at least one co-catalyst followed by polymerization of isomerized α-olefin monomers mainly containing no branched ones. Resulting polymer may be used as agent enhancing flow of hydrocarbons through conducting canals.

EFFECT: improved performance characteristics of polymers.
