Notes: Synthesis and living anionic ring-opening polymerization of 1,1-dipropylsilacyclobutane are reported. High molecular weight poly(dipropylsilylenepropylene) up to Mn = 83900 g/mol (SEC/PS standards) with low polydispersity (Mw/Mn = 1.11 to 1.22) was obtained at -20°C. End functionalization of poly-(dipropylsilylenepropylene) with chlorodimethylvinylsilane and synthesis of block copolymers with styrene was achieved. The polymers were characterized with NMR, SEC, MALDI-TOF and DSC.
