A new initiating system for the living polymerization of vinyl ethers leading to hydroxy-terminated polymers

The reaction of trimethylsilyl iodide (TMSI) with 1,3-dioxolane (DXL) leads to the formation of 1-trimethylsiloxy-4-iodo-3-oxabutane. In combination with tetrabutyl ammonium triflate this compound can be used as an initiator for the polymerization of vinyl ethers. According to a living polymerizatio...

Description
Summary:The reaction of trimethylsilyl iodide (TMSI) with 1,3-dioxolane (DXL) leads to the formation of 1-trimethylsiloxy-4-iodo-3-oxabutane. In combination with tetrabutyl ammonium triflate this compound can be used as an initiator for the polymerization of vinyl ethers. According to a living polymerization mechanism, the polymers are characterized by controlled molecular weights and narrow molecular weight distributions. The trimethylsiloxy head group originating from the initiation reaction is easily transformed into a primary hydroxyl function by hydrolysis. Graphs, spectra. 10 ref.--AA
