| titleOfInvention | Method of obtaining polyethylene and copolymers of ethylene with alpha-olefins with wide molecular mass distribution |
| abstract | FIELD: chemistry. n SUBSTANCE: present invention relates to the method of obtaining polyethylene and copolymers of ethylene with alpha-olefins with a wide range of molecular mass distribution, using Ziegler type supported catalyst, containing a compound of a transition metal on a magnesium containing carrier. The process is carried out in the presence of a catalyst which contains a vanadium compound (VCl 4 , VOCI 3 , V(OR) x Cl 3 - x ) on a magnesium containing carrier, which is obtained from reacting a solution of organomagnesium compound with the formula: Mg(C 6 H 5 ) 2 n MgCl 2 mR 2 O, where: n=0.37-0.7, m=2, R 2 O is ether with R=i-Am, n-Bu, with a product of reacting alkylchlorosilane with the formula: R' k SiCl 4-k , where R is alkyl or phenyl, k=0, 1, 2, and silicon tetraalkoxide Si(OEt) 4 . Dialkylaromatic ether D is used in the organomagnesium compound MOC. Polyethylene and copolymers of ethylene and alpha-olefins with wide molecular-mass distribution are obtained using the above described catalyst in conjunction with organoaluminum co-catalyst at 50-100°C in a medium of hydrocarbon diluent. Hydrogen, taken in amount of 5-50 vol.%, is used as the regulator of molecular mass of the polymer. n EFFECT: during polymerisation of ethylene on this catalyst, polyethylene is produced with high packed density and narrow particle size distribution, as well as wide molecular mass distribution. n 3 cl, 5 ex, 1 tbl |
