Avoidance of coloured contaminations during the preparation of ultra-high molecular weight polyethylenes by means of a catalyst containing titanium. |
摘要 |
The invention relates to a process for the preparation of ultrahigh-molecular-weight ethylene polymers in the gas phase in a fluidised bed of particulate polymer by the continuous introduction of the appropriate monomers into a polymerisation system at from 60 to 120 DEG C and at from 5 to 60 bar in the presence of a reaction product of a titanium-containing catalyst and an antistatic and in the presence of a monohydric or polyhydric alcohol, and to an ultrahigh-molecular- weight ethylene polymer prepared by said process.
