    摘要: A method for preparing Ziegler catalysts is disclosed wherein a mixture (A) containing the product resulting from mixing in an inert hydrocarbon diluent (1) a hydrocarbon soluble magnesium alkyl compound in said hydrocarbon solvent, (2) an aliphatic alcohol or carbon dioxide and (3) a titanium compound is reacted with (B) a reducing halide source in said hydrocarbon solvent. Components (A) and (B) are mixed at a constant initial temperature. When the magnesium concentration in component (A) and the metal concentration in component (B) are relatively low, the resultant polymer has a relatively narrow particle size distribution whereas when said concentration is relatively high, the resultant polymer has a relatively broad particle size distribution. When the ratio of the number of moles of aliphatic alcohol:total number of hydrocarbyl groups attached to the metal atom in component (1) is relatively low, the resultant polymer has a relatively small average particle size. When the ratio of the number of moles of aliphatic alcohol:total number of hydrocarbyl groups attached to the metal atom in component (1) is relatively high, the resultant polymer has a relatively large average particle size.

These thermoplastic compositions have improved processability. Processes for fabricating articles from them are described. The articles made with these compositions have improved properties such as low temperature impact strength, improved percent elongation to break, greater stiffness, and improved weld line strength, making them useful for applications requiring both strength and flexibility in low temperature environments, such as automotive components and facia.
