| titleOfInvention | Widen the molecular weight distribution of the polyolefine material manufactured in horizontal stirred gas phase reactor phase reactor |
| abstract | The invention discloses the molecular weight widening the polyolefine material manufactured in horizontal stirred gas phase reactor phase reactor.Particularly, the invention discloses olefine polymerizing process, described method comprises the high activated catalyst using and be injected in reactor front end, carries out the vapour phase polymerization of at least one olefinic monomer, to produce solid polymer particles in more than one polymeric area of one or more polymerization reactor.According to method of the present invention, apply different hydrogen to reactor and cause creating very different molecular weight from olefin ratio, therefore broaden the molecular weight distribution of produced polymkeric substance. |
