| titleOfInvention | Catalyst and method for producing ultra-high molecular weight polyethylene using this catalyst |
| abstract | FIELD: chemistry. n SUBSTANCE: invention relates to a method for producing ultra-high molecular weight polyethylene (UHMWPE) using the supported ziegler type catalyst comprising a transition metal compound on a magnesium-containing support. The catalyst for producing ultra-high molecular weight polyethylene-UHMWPE contains a transition metal compound on a magnesium-containing support, which is produced by reacting a solution of an organomagnesium compound of the composition: Mg (C 6 H 5 ) 2 n MgCl 2 mR 2 O, where: n = 0.37-0.7, m = 2, R 2 O is a simple ether with R = i-Am, n-Bu, with the reaction product of alkylchlorosilane of the composition: R' k SiCl 4-k , where: R' - alkyl or phenyl, k = 0, 1, 2, and silicon tetraalkoxide Si (OEt) 4 taken at the molar ratio R' k SiCl 4-k , / Si (OEt) 4 = 50-2. As the transition metal compound, a mixture of titanium compounds (TiC 4 or Ti (OEt )2 Cl 2 ) and vanadium (VCl 4 , VOCl 3 ). The method for producing ultra-high molecular weight polyethylene UHMWPE in the suspension mode in a hydrocarbon diluent medium is carried out at a polymerization temperature above 70°C in the presence of an organoaluminum cocatalyst using the said catalyst. Herewith an ultra-high molecular weight polyethylene with a molecular weight in the range of 2.5⋅10 6 up to 8⋅10 6 g/mol. n EFFECT: using high polymerisation temperatures, which allows to increase reactor productivity and the possibility of producing ultra-high molecular weight polyethylene with the required molecular weight. n 3 cl, 1 tbl, 7 ex |
