Exxon gains gas-phase patent, makes LLDPE
Exxon chemical says it has made linear low-density polyethylene (LLDPE) using metallocene catalysts at its world-scale gas-phase plant in Mont Belvieu, TX. Exxon also says it has received a broad US patent that covers the use of metallocenes in gas-phase reactors that use condensing mode technology and that it plans to license the know-how. The moves, say industry experts, greatly strengthen Exxon`s position in metallocenes, particularly in pushing metallocene-based PE into commodity markets. The use of gas-phase technology {open_quotes}had to happen{close_quotes} to allow metallocene polymers to compete as commodities, says David Highfield, v.p. at Catalyst Consultants (Spring House, PA). {open_quotes}It`s very important and very significant in widening the scope of [metallocene] technology.{close_quotes}
