New class of polyolefin catalyst

Published on 2003-04-03. Author : SpecialChem


The Dow Chemical Company and Symyx Technologies, Inc. announced that, for the first time, a new class of single-site catalysts for olefin polymerization has been discovered through the application of fully integrated high-throughput screening methodology. The discovery of the new amide-ether based hafnium catalyst class validates the use of the technique as a time-saving research tool, and has broad implications for Dow's ability to greatly accelerate the discovery and commercialization of next generation catalysts for olefin polymerization. The research results will be published in the April 9, 2003, issue of the Journal of the American Chemical Society (JACS), Vol. 125; Issue 14.

Conventional methods of polyolefin catalyst research involve an expensive, time-consuming "trial and error" process with unpredictable and often disappointing results. Using the fully integrated high throughput primary and secondary screening methodology, however, Dow and Symyx researchers are now able to analyze large quantities of metal-ligand combinations, identify the most promising catalytically active systems, and reject those that are inactive, all in a matter of hours. As a result, a much broader range of catalysts candidates and conditions can be evaluated, allowing time and resources to be directed toward maximizing the potential of the most promising ones.

Dow and Symyx have collaborated in the field of high-throughput discovery of polyolefin catalysts since January 1999. Dow is actively developing several catalysts discovered by Symyx under that collaboration.

Dow is a leading science and technology company that provides innovative chemical, plastic and agricultural products and services to many essential consumer markets.

Symyx develops and applies high-speed combinatorial technologies to the discovery of materials for life science, chemical and electronics applications. Symyx provides research services through its Industry Collaborations business, licenses discovered materials and patents through its Licensing business, and sells select instruments and software through its Discovery Tools® business.
