Abstract
PURPOSE: To improve the stereoregularity of a produced polymer, by carrying out the polymerization of an α-olefin by use of a ternary catalyst containing an organic Al compound, an Mg compound-supported catalyst and an aromatic ester of a sec. or tert. alcohol.
CONSTITUTION: In polymerizing a C3WC12 α-olefin by use of a catalyst system containing (A) an organoaluminum compound such as triethyl-aluminum, (B) a reaction product of a magnesium compound such as anhydrous magnesium chloride and a titanium tetrachloride and (C) a Lewis base; as said Lewis base is used an aromatic carboxylic acid ester of a C3WC15 sec. or tert. alcohol, represented by the formula, wherein R1 is H or a hydrocarbon group, R2 and R3 are hydrocarbon groups and Z is H, a hydrocarbon group, alkoxyl or amino. Examples of this ester include iropropyl benzoate and tert.-butyl p-anisate. According to this process, the stereoregularity of a polymer can be improved, while the catalyst activity is maintained at high levels.
