| Abstract: | Summary poly(1-Phenyl-1-sila-cis-pent-3-ene) (I) has been prepared by the anionic ring opening polymerization of 1-phenyl-1-sila-cyclopent-3-ene (II). This reaction is co-catalyzed by n-butyl-lithium and HMPA in THF at low temperature. I has been characterized by 1H, 13C and 29Si NMR, IR, UV, GPC and TGA. The low molecular weight of l permits end group analysis. Pyrolysis of l gives significant char yields. |
