PROCESS FOR THE PRODUCTION OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE |
摘要 |
The invention relates to a process for the production of ultra high molecular weight polyethylene having a molecular weight between 1000000 and 10000000 g/mol, an average particle size (D) in the range between 50 and 250 [mu]m and a bulk density in the range between 100 and 350 kg/min the presence of a catalyst system that comprises (I) the solid reaction product obtained from the reaction of: a) a hydrocarbon solution containing 1) an organic oxygen containing magnesium compound or a halogen containing magnesium compound and 2) an organic oxygen containing titanium compound and b) an organo aluminium halogen compound having the formula AIRXin which R is a hydrocarbon radical containing 1-10 carbon atoms, X is halogen and 0<n<3 and (II) aluminium compound described by formula AlR, in which R is a hydrocarbon radical containing 1-10 carbon atoms. |
