Epub 2008 Feb 5.Syntheses of vinylsilyl alcohols having one to three vinyl moieties and their use as initiators for ethylene oxide polymerizations are discussed. Poly(ethylene oxide) oligomers with vinylsilanes at one end and a hydroxyl group at the other were prepared in base-catalyzed reactions. Molecular weights determined from 1H NMR and gel permeation chromatography were close to the targeted values. Carboxylic acid functional poly(ethylene oxide) oligomers were prepared from ene-thiol addition reactions of mercaptoacetic acid across the vinylsilane terminus. Read More
