Method for producing high-density polyethylene |
| abstract |
(57) [Problem] To provide a method for producing high-density polyethylene capable of increasing polymerization activity per catalyst and obtaining high-density polyethylene excellent in moldability. In a method for producing high-density polyethylene by a multistage slurry polymerization method including a low molecular weight polyethylene polymerization step and a high molecular weight polyethylene polymerization step, a polymerization liquid obtained in a final polymerization step is obtained by solid-liquid separation. Collection liquid 3 A method for producing high-density polyethylene, comprising circulating 5% or more as a polymerization solvent in a low-molecular-weight polyethylene polymerization step. |
