Continuous gas-phase fluidized bed process for producing ethylene homopolymers and copolymers |
| abstract |
(57) [Summary] [Objective] A (co) polymer having a high bulk density can be produced in a high yield without the formation of wall deposits and debris, of 0.87 to 0.97 g / cm 3 . PROBLEM TO BE SOLVED: To provide a novel continuous gas phase fluidized bed method for producing ethylene homopolymers and ethylene copolymers having a density d. To make a (co) polymer of preselected density d, the upper layer equation I: And lower layer equation II: [However, T RH represents the maximum reaction temperature in ° C .; T RN Represents the minimum reaction temperature in ° C; d'represents the value of the density d of the (co) polymer to be produced]] a continuous (co) polymerization carried out at a temperature T R within a range limited by Gas phase fluidized bed method. |
