Title: PROCESS FOR THE PRODUCTION OF ETHYLENE POLYMERS
Abstract:
The present invention relates to a process for the production of ethylene polymers in a tubular reactor comprising reacting in said tubular reactor a feed composition comprising ethylene and one or more composition comprising one or more cyclic olefin wherein the cyclic olefin is a compound having the structure of Formula (I): wherein R may be a moiety comprising≥1 and≤10 carbon atoms; wherein R1 and R2 may each individually be hydrogen or a moiety comprising≥1 and ≤5 carbon atoms, R1 and R2 may be the same or different; wherein • the tubular reactor may be operated at a pressure of≥ 200 and ≤ 280 MPa; • the average reaction peak temperature may be≥ 220°C and ≤ 300°C; • the composition comprising one or more cyclic olefin may be fed to the reactor in one or more feed inlet of said tubular reactor; and • said cyclic olefin may be fed to the tubular reactor in quantities of≤ 1.0 mol %, with regards to the total feed composition. Such process allows for the production of ethylene polymers having a high density and a high purity.
