Abstract:
     The catalyst contains (a) catalyst body, (b) sub-catalyst and (c) selectivity controlling agent, where (a) is a solid component, comprising Mgcl2, Ticl4 and electron donor (b) is trialkyl aluminium, (c) is a complex compound of strong selective controlling agent and weak agent. This catalyst is used in alpha-olefine monomer polymerization.
