Process for Producing a Polyethylene Composition Comprising Bimodal or Multimodal Polyethylene
11 Jan 24
A process for preparing a polyethylene composition made from or containing bimodal or multimodal polyethylene in an extruder device including the steps of (i) mixing a bimodal or multimodal polyethylene having a density from 0.940 g/cm3 to 0.968 g/cm3, in the form of a polyethylene powder, with an additive, in a mixing device at a temperature from 10° C. to 100° C. without melting the polyethylene powder; (ii) melting and homogenizing the mixture within the extruder device, thereby forming a molten polyethylene composition; and (iii) pelletizing the molten polyethylene composition, and further (iv) adding a liquid made from or containing an organic peroxide, in an amount from 20 ppm to 200 ppm of organic peroxide with respect to the polyethylene powder, to the polyethylene powder at a position where mixing occurs and the polyethylene powder has a temperature of from 10° C. to 100° C.

Suspension process for preparing ethylene copolymers in a reactor cascade
5 Dec 23
A process for preparing a multimodal ethylene copolymer in suspension in a reactor cascade including a first polymerization reactor and subsequent polymerization reactor(s) including polymerizing ethylene and C3-C12-1-alkenes and forming a suspension of multimodal ethylene copolymer particles in a suspension medium made from or containing a diluent, transferring the suspension into a separator, wherein the suspension is separated into multimodal ethylene copolymer particles and recovered suspension medium, purifying part of the recovered suspension medium for producing purified components of the recovered suspension medium, and recycling part of the purified components of the recovered suspension medium to the first polymerization reactor of the reactor cascade, wherein the purified components of the recovered suspension medium recycled to the first polymerization reactor and made from or containing the diluent, undergo catalytic hydrogenation before being introduced into the first polymerization reactor.
