Polymerization of 2,3-bis(trimethylsilyl)-1,3-butadiene in hexane/HMPA catalyzed by n-butyllithium yields trans-1,4-poly<2,3-bis(trimethylsilyl)-1,3-butadiene>.This polymer has been characterized by 1H, 13C and 29Si NMR as well as IR spectroscopy and elemental analysis.The stereochemistry of the carbon-carbon double bonds has been established by protodesilation of the polymer with HI.The molecular weight distribution of the polymer has been determined by gel permeation chromatography and its thermal stability by thermogravimetric analysis.
