| 摘 要： | 介绍了在30万t／a聚丙烯装置上生产双向拉伸聚丙烯薄膜专用料的工艺条件优化情况。通过分析影响产品熔体流动速率（MFR）、等规度、相对分子质量及其分布等主要物性的工艺条件，提出优化指标及措施如下：控制产品的MFR为0．280～0．320g／min；调整系统三乙基铝（TEAL）／外给电子体（Donor）质量比为28、TEAL／丙烯质量比为0．16×10^-1，使产品的等规度控制在95．0％-97．0％；调整环管反应条件、H2用量及反应分配率，使产品相对分子质量分布控制在4．62—5．45。 |
| 关 键 词： | 聚丙烯 双向拉伸聚丙烯 薄膜 环管反应器 熔体流动速率 等规度 相对分子质量及其 分布 |

| Abstract: | The process conditions optimization for producing biaxially oriented polypropylene(BOPP) were introduced in a 300 kt/a polypropylene(PP) unit.Based on the analysis of process conditions which influenced the melt flow rate(MFR),isotacticity,relative molecular mass and its distribution of the product,the optimal indexes and countermeasures were proposed.The isotacticity should be controlled to 95.0%-97.0% by regulating MFR to 0.280-0.320g/min,mass ratio of triethyl aluminum(TEAL) to Donor to 28 and mass ratio... |
| Keywords: | polypropylene biaxially oriented polypropylene film loop reactor melt flow rate isotacticity relative molecular mass and its distribution |
