摘要： The present invention relates to a solid catalyst component comprising magnesium, titanium, halide, and internal electron donor compounds comprising dilakylurea, malonate, succinate, and 1,3-diether, wherein the succinate amount is less than about 30% by mol with respect to the total amount of electron donor, the molar ratio between succinate and 1,3-diether is in the range of about 0.1 - 0.5, and the molar ratio between malonate and 1,3-diether is in the range of about 0.5 - 2.5. The catalyst component according to present invention provides highly isotactic polypropylene polymer with broad molecular weight distribution.

摘要： Disclosed is a method of removing dimethyl ether from an ethylene and/or propylene containing stream. Dimethyl ether is removed at a high pressure, preferably in a distillation column. The high pressure separation has the benefit of providing a relatively low bottoms temperature separation, while allowing for recovery of a highly concentrated ethylene and/or propylene stream.
