As the demand for new polymeric materials with superior performance properties that can be used to support existing, new, and yet-to-be discovered technologies continues unabated, new paradigms are required that have the potential to dramatically change the range and pace at which olefin commodity feedstocks can be converted into new classes of polyolefins, hydrocarbons and specialty chemicals of commercial and societal value. This talk will focus on our efforts to expand the available set of 'tools' that can be wielded in programmed fashion to produce a near continuum of different polyolefin materials that exist between two different limiting stereochemical microstructures, co-polymer compositions or polymer architectures � all from a single catalyst and with a high degree of precision. When combined with living coordinative chain transfer polymerization (LCCTP) that employs an excess of a main group metal alkyl as 'surrogate' chain growth sites, practical (> kilograms) quantities of a vast array of new polyolefin materials with unique (micro)structures and technologically-interesting properties are now available to support a new period of discovery and innovation.
