Abstract
Abstract New olefin polymerization catalysts are disclosed which are prepared by mixing (A) the product obtained by contacting (1) a halogen-containing, or a halogen free, oxygen-containing organic compound of Ti, V or Zr, with (2) a hydrocarbon-insoluble solid product containing at least metal M and halogen and resulting from decomposition of a complex having the formula (I) MX 2 .nAlRX 2 .pAlX 3 to M dihalide, or to a product containing M dihalide. In formula (I): M is Ba, Ca, Mg or Mn; X is chlorine or bromine in the case of MX 2 and AlX 3 , and chlorine, bromine or alkoxy group in the case of AlRX 2 ; R is a hydrocarbon radical containing from 1 to 20 carbon atoms; n is a number from 1 to 4, inclusive; p is a number from 0 to 1, inclusive; 1≦n + p≦4; with (B) an organometallic compound of a metal belonging to Groups I-III of the Mendelyeev Periodic Table, In the decomposition product of formula (I) M in the M dihalide has the same significance as M in formula (I).
