摘要：

The Dow Chemical Company has developed a new family of polyolefins using Constrained Geometry Catalyst Technology (CGCT). The technology is being commercialized under the tradename INSITE(TM). These INSITE(TM) technology polymers are characterized by a narrow molecular weight and comonomer distribution. In general, a narrow molecular weight and comonomer distribution would be expected to improve physical properties at the expense of processability. The unique molecular structure of INSITE(TM) technology polymers delivers increased physical properties without sacrificing processability. The improved processability is believed to be the result of significant amounts of long-chain branching. The structure/activity relationships of the family of Constrained Geometry catalysts which give rise to these unique polymers will be discussed.
