摘要： The present invention relates to a solid catalyst component for the polymerization of olefins CH2=CHR in which R is hydrogen or a hydrocarbyl radical with 1-12 carbon atoms, comprising a titanium compound, having at least a Ti-halogen bond and an electron donor compound supported on an Mg halide, in which said electron donor compound is selected from esters of malonic acids of formula (I), wherein R1 is a C5-C20 linear or branched alkyl, a C5-C20 cycloalkyl, a C7-C20 arylalkyl or alkylaryl group; R2 and R3, equal to or different from each other, are C1-C3 alkyl, cycloalkyl. Said catalyst components when used in the polymerization of olefins, and in particular of propylene, are capable to give high yields and polymers having high insolubility in xylene.

摘要： Catalysts for the polymerization of olefins are disclosed, which comprise the reaction product of: (A) a bridged and/or substituted cyclopentadienyl compound of titanium, zirconium or hafnium; (B) an organometallic aluminum compound of the formula (II) Al(CH2-CR4R5R6)wR7yHz, wherein in the (CH2-CR4R5R6) groups, which are the same or different, R4 is an alkyl, alkenyl or arylalkyl group having from 1 to 10 carbon atoms, R5 is an alkyl, alkenyl, aryl, arylalkyl or alkylaryl group having from 3 to 50 carbon atoms which is different from a straight alkyl or alkenyl group and, optionally, R?4 and R5¿ fused together can form a ring having from 4 to 6 carbon atoms, R6 is hydrogen or an alkyl, alkenyl or arylalkyl group having from 1 to 10 carbon atoms, the R7 substituents, same or different, are alkyl, alkenyl, aryl, arylalkyl or alkylaryl radicals containing from 1 to 10 carbon atoms and, optionally, can contain Si or Ge atoms, w is 1, 2 or 3, z is 0 or 1, y = 3-w-z; and (C) water. The molar ratio aluminum/water is comprised between 1:1 and 100:1. These catalysts show an improved activity with respect to known catalysts wherein an aluminum compound different from those of the above formula is used.

摘要： Multistage process for the polymerization of one or more olefins of the formula CH2=CHR, in which R is hydrogen or an alkyl, cycloalkyl or aryl group having from 1 to 10 carbon atoms, comprising: (A) a first stage of polymerization, in which a first olefin polymer is prepared in the presence of titanium catalyst or vanadium catalyst; (B) a treatment stage in which the catalyst used previously is deactivated and in which a metallocene compound is supported on the olefin polymer produced in stage (A); and (C) a second stage of polymerization in which one or more olefins are polymerized in the presence of the product obtained from stage (B).
