摘要
New components of catalysts for polymerizing alpha-olefins, and the catalysts formed from the new components are disclosed. Said catalyst components are prepared by reacting Ti compounds with a carrier in the form of spheroidal particles of specified characteristics and which consists of or comprises an Mg compound, or mixture of Mg compounds of the formula XnMg(OR)2-n (I) in which 0/=n/=2, R is an alkyl, aryl, cycloalkyl radical containing from 1 to 20 carbon atoms, X is halogen or a group OR' in which R' is an alkyl, aryl or cycloalkyl radical containing from 1 to 20 carbon atoms and is the same or different from R in formula (I).
