| titleOfInvention | Polymerization method of ethylene |
| abstract | An improved process for the polymerization of ethylene is provided. I) a solid catalyst comprising Ti, Mg and halogen; ii) at least one trialkylaluminum compound of the formula AlR 3 , wherein each R is independently a C2-C20 alkyl group. A first activator, and iii) a second activator that is at least one alkylaluminum chloride of the formula AlR ′ 2 Cl where each R ′ is independently a C 2 -C 20 alkyl group. At any time corresponding to less than 10 ppm by weight of the second activator continuously or semi-continuously without pre-contacting with the solid catalyst and with respect to the polyethylene production rate. In the above-mentioned method, it is directly introduced into the polymerization reactor at the maximum introduction rate. [Selection] Figure 3 |
