    摘要: Catalytic system for polymerization of lower alpha alkene including a selectivity control agent which consists of naturally derived pure isomers of tartrates such as esters of (2-R,3-R)-dihydroxy-butane-1,4dicarboxylic acid or (2-S,3-S)-dihydroxybutane-1,4-dicarboxylic acid. The molar ratio of the optically pure isomers of the tartrates to titanium being 0.0375 to 1.5.

    摘要: Single step process for the preparation of lower α-alkene polymerisation heterogeneous solid catalyst, wherein the procatalyst is obtained by reacting organomagnesium precursor and titanium tetrahalide or titanium haloalkoxo species of the formula Ti(OR)m Xn, with a hydrocarbon or halohydrocarbon solvent and internal electron donor and optionally an acid halide under microwave irradiation of 300 to 1200 W. The mole ratio of the organomagnesium precursor to the titanium tetrachloride or titanium haloalko species is 1:6 to 1:20 and the mole ratios of the electron donor and acid halide to titanium is 0.3 to 1.5 and 0.02 to 0.2, respectively.
