The Dow Chemical Company is the world's largest practitioner of homogenous catalysis including production of polyolefins. Olefin polymerization with homogeneous catalysts allows for unprecedented control over polymer composition and microstructure. This talk will discuss the development of constrained geometry catalysts within Dow for the production of ethylene-based copolymers such as ethylene-styrene and ethylene-1-octene. Particular emphasis will be givin to the recent research aimed at modifying structures of catalysts to affect both the polymer molecular weight and the reactivity toward alpha-olefins during ethylene/alpha-olefins copolymerization reactions.
