ABSTRACT:
Catalyst for the stereospecific polymerization of alpha-olefins of 3 or more carbon atoms comprising an organoaluminum component and a component prepared from halogen-containing compound of titanium(IV), organic electron donor, and a pretreatment product of components comprising magnesium alcoholate, organosilicon compound, and optionally, one or more Group II or IIIA metal alkyls, pretreatment modifiers such as a mineral acid or anhydride of sulfur, organometallic chalcogenide derivative of hydrogen sulfide, organic acid or organic acid ester, or combination of metal alkyl and modifier. Preferably, the product obtained from such materials is mechanically activated prior to polymerization use.
