| titleOfInvention | A kind of For Propylene Pre-polymerization method |
| abstract | The invention provides a kind of For Propylene Pre-polymerization method, the method adopts catalyst for polymerization of propylene, activator, external electron donor and propylene are at normal temperatures, Continuous Contact in pre-polymerization reactor polymerization reaction take place, slurries after prepolymerization carry out liquid-phase bulk or vapour phase polymerization again, this prepolymerization technology flow process is simple, process control procedure is simple and reliable, working cost is low, be specially adapted at Innovene, Novolen, Unipol etc. are without the gas-phase polymerization polypropylene process application of prepolymerization technology, recurrent temperature fluctuation in these gas phase reaction process can be solved, polymer lumps, the problems such as in polymer powders fine powder content is high, and the ability of these device development more high added value polymkeric substance of high rubber content can be improved. |
