摘要：

Cr/SiO2 or Phillips-type catalysts are nowadays responsible for a large fraction of all polyethylene (HDPE and LLDPE) worldwide produced. In this review, several key-properties of Cr/SiO2 catalysts will be discussed in relation to their polymerization characteristics. It will be shown how the polyolefin properties can be controlled via rational catalyst design. (C) 1999 Elsevier Science B.V. All rights reserved.
