| titleOfInvention | Catalyst preparation process and ethylene polymerization and ethylene-alpha-olefin copolymerization processes utilizing this catalyst |
| abstract | FIELD: polymerization catalysts. n SUBSTANCE: invention, in particular, relates to preparation of Ziegler-type catalyst comprising transition metal (titanium or vanadium) compound on magnesium-containing carrier. Carrier is prepared via interaction of organomagnesium compound-containing solution depicted by formula Mg(C 6 H 5 ) 2 ·nMgCl 2 ·mR 2 O, wherein n=0.37-0.7, m=2, and R 2 O is ether with R = i-Am or n-Bu, with chlorination agent, namely X k SiCl 4-k , wherein X is OR' or R', in which R can be C 1 -C 4 -alkyl or phenyl, and k=1-2. Above named polymerization and copolymerization process are carried out with catalyst of invention in combination with cocatalyst. n EFFECT: reduced size distribution range of polymers and enabled average particle size control. n 3 cl, 1 tbl, 13 ex |
