| Abstract: | The group transfer polymerization (GTP) of alkyl methacrylates has been studied using hydrosilane and tris(pentafluorophenyl) borane (B(C6F5)(3)) as the new initiation system. For the B(C6F5)(3)-catalyzed polymerization of methyl methacrylate (MMA) using triethylsilane, tri-n-butylsilane (nBu(3)SiH), dimethylphenylsilane (Me2PhSiH), triphenylsilane, and triisopropylsilane, nBu(3)SiH and Me2PhSiH were suitable for producing well-defined polymers with predicted molar masses and a low polydispersity. The livingness of the GTP of MMA using Me2PhSiH/B(C6F5)(3) was verified by the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) measurement of the resulting polymers, kinetic analyses, and chain extension experiments. The B(C6F5)(3)-catalyzed GTP using Me2PhSiH was also applicable for other alkyl methacrylates, such as the n-propyl, n-hexyl, n-decyl, 2-ethylhexyl, iso-butyl, and cyclohexyl methacrylates. The in situ formation of the silyl ketene acetal by the 1,4-hydrosilylation of MMA was proved by the MALDI-TOF MS and H-2 NMR measurements of the polymers obtained from the B(C6F5)(3)-catalyzed GTPs of MMA with Me2PhSiH or Me2PhSiD, which was terminated using CH3OH or CD3OD. |
