Control of oligomer level in low pressure polyethylene reactor systems

摘要

In accordance with the invention, the process comprises substantially eliminating distributor plate fouling in fluid bed reactor alpha olefin polymerizations, by removing oligomers from the recycle feeds to the fluid bed reactor. In accordance with the invention, the process comprises substantially eliminating gel production in the low pressure production of polymers and copolymers of ethylene. Unexpectedly, the process of the invention, which substantially eliminates distributor plate fouling also results in polymer products which are substantially free of gels.
