MULTIMODAL POLYOLEFIN PIPE |
| 摘要 |
A solution polymerization process in a series or parallel of two or more reactors at different temperatures is used to prepare a multimodal polyolefin resin of narrow molecular weight distribution. This resin is used to manufacture melt extruded pipe that has an improved performance at elevated temperatures and an improved hydrostatic design.
