Shuttling Polyolefins to a New Materials Dimension

摘要

The past 20 years have seen unparalleled developments in the design and development of single-site catalysts for the production of polyolefins (1, 2), plastic materials that are presently generated on a scale approaching 100 million tons per year. These new catalyst systems display comparable activities to classical catalysts but also have the potential to control the molecular weight, molecular weight distribution, and micro-structure of the polymer, thus providing access to new materials without major penalties on productivity.
