titleOfInvention | Process for controlling the molecular weight of poly(trialkylsilylpropyne) polymers |
abstract | The present invention is a process for polymerizing trialkylsilylacetylene derived monomers to form the corresponding poly(trialkylsilylacetylene) polymer. The polymerization reaction is carried out in the presence of an organic solvent over a catalyst comprising a halide of a transition metal of group Vb or Vlb. The molecular weight of the resultant polymer is decreased by adding to the reaction mixture, in a concentration between about 0.5-25 wt.%, a compound having the structural formula:n wherein each R is independently methyl, C 2-4 alkyl or phenyl, and n is from 1 to 100. |
