| Abstract: | This paper analyzed the process flow and the phase separation characteristics of low density polyethylene at different pressures,temperatures and relative molecular mass.The scheme of technological operation was optimized,which enabled the resultant melt polymer to be effectively separated in the separation system.The hidden trouble in safety caused by polymer fouling could be prevented after decelerating the fouling speed in the equipment. |

| Keywords: | low density polyethylene phase equilibrium phase separation |
