In this work we report the synthesis of alpha,omega vinyl terminated PDMS (B2V) by employing a novel bifunctional initiator. The synthesis involves high-vacuum anionic polymerization techniques and the sequential addition of specific reagents, starting from commercial diglycidylether terminated poly(dimethylsiloxane) (PDMS-DGE). The final reaction product was characterized by conventional analytical techniques, such as SEC, 1H-NMR and FTIR.
