PROCESS FOR THE PRODUCTION OF ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE
摘要
<p>The invention relates to a process for the production of ultra high molecular weight polyethylene having a molecular weight between 1000000 g/mol and 10000000 g/mol, an average particle size (D50) in the range between 50 and 250μm and a bulk density in the range between 100 and 350 kg/m3 in 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 AIRn X3-n in which R is a hydrocarbon radical containing 1-10 carbon atoms X is halogen and 0<n<3 and (II) an aluminium compound having the formula AIR3 in which R is a hydrocarbon radical containing 1-10 carbon atom.</p>
