Univation Technologies的先进催化剂工程技术提供了在单个气相反应器中生产具有双峰分子量分布和双峰组成分布的聚乙烯的能力。本文将讨论这些工程聚乙烯产品的结构-性能-工艺关系。具有双峰分子量分布的高密度聚乙烯（HDPE）聚合物的实例将证明工程催化剂在高分子量膜生产中的实用性。具有宽共聚单体组成分布的线性低密度聚乙烯（LLDPE）聚合物的实例将证明工程催化剂用于高强度膜应用的实用性。具有双分子量分布和可控共聚单体分布的HDPE聚合物的实例将展示Univation最新设计的催化剂用于高性能管道应用的能力。
Advanced catalyst engineering from Univation Technologies provides the capability to produce polyethylene with bimodal molecular weight distribution and bimodal composition distribution in a single gas phase reactor. This paper will discuss the structure-property-process relationship for these engineered polyethylene products. Examples of High Density Polyethylene (HDPE) polymers with bimodal molecular weight distribution will demonstrate the utility of the engineered catalysts in high molecular weight film production. Examples of Linear Low Density Polyethylene (LLDPE) polymers with broad comonomer composition distribution will demonstrate the utility of the engineered catalysts for high strength film applications. Examples of HDPE polymers with bidmoal molecular distribution and controlled comonomer distribution will demonstrate the capability of Univation's latest engineered catalysts for high performance pipe applications.
