    • The invention relates to a process for the preparation of polyolefins by polymerizing olefins of the formula CH.sub.2 CHR in which R=H or C.sub.1 -C.sub.10 alkyl, on their own or as a mixture, if appropriate together with C.sub.4 -C.sub.12 .alpha.,.omega.-diolefins, in solvents, liquid monomers or the gas phase, at temperatures between -50.degree. and 200.degree. C., using a catalyst system composed of a soluble, halogen-containing transition metal compound of the general formula(cyclopentadienyl).sub.2 Me R Halin which R is cyclopentadienyl or a C.sub.1 -C.sub.6 alkyl radical or a halogen, in particular chlorine, Me is a transition metal, in particular zirconium, and Hal is a halogen, in particular chlorine, and a compound, containing aluminum, of the aluminoxane type having the general formulaeAl.sub.2 OR.sub.4 (Al(R)--O).sub.nfor a linear aluminoxane and/or(Al(R)--O).sub.n+2for a cyclic aluminoxane, in which n is a number from 4 to 20 and R is a methyl or ethyl radical, preferably a methyl radical.
    • 本发明涉及一种制备聚烯烃的方法,该方法通过将其中R = H或C 1 -C 10烷基的式CH 2 CHR的烯烃自身或作为混合物如果合适地与C4-C12α,ω-二烯烃, 在溶剂,液体单体或气相中,在-50℃和200℃之间的温度下,使用由可溶性的含卤素的通式(环戊二烯基)2 Me R Hal的过渡金属化合物组成的催化剂体系,其中 R是环戊二烯基或C 1 -C 6烷基或卤素,特别是氯,Me是过渡金属,特别是锆,Hal是卤素,特别是氯,以及含有铝的化合物,铝氧烷类具有 对于环状铝氧烷,线性铝氧烷和/或(Al(R)-O)n + 2的通式为Al 2 OR 4(Al(R)-O)n,其中n为4至20的数,R为 甲基或乙基,优选甲基。
