| 英文摘要 | A novel mgcl2-supported ziegler-natta catalyst using poly(propylene glycol) dibenzoate (ppgdb) as the internal electron donor for propylene polymerization was prepared. the catalyst exhibited comparable activity and stereoselectivity with that using normal phthalate as electron donor but rather broader molecular weight distribution of resulting polypropylene. examination of the interaction between ppgdb and mgcl2 by using infrared spectroscopy showed that both c=o and c-o-c of ppgdb could coordinate to mgcl2. this bidental coordination nature of ppgdb was suggested to be the reason for wide molecular weight distribution of the polypropylene obtained. |
