Process for the preparation and uses of derivatives of esters of &agr;-methylene-&bgr;-hydroxy acids
Patent number: 6310237Abstract: A process for the preparation of derivatives of halo-but-2-enoic acids and esters high in 2-ene content, several of which are novel. The esters and their derivatives are useful as promoters for the polymerization of ethylene or the copolymerization of ethylene with &agr;-olefins and, optionally, nonconjugated polyenes. The promoters can also be combined with transition metal compounds, e.g., vanadium, to form combination promoter-catalyst compounds.Type: GrantFiled: July 18, 2000Date of Patent: October 30, 2001Assignee: Uniroyal Chemical Company, Inc.Inventors: Xu Wu Feng, Walter Nudenberg -
