| Popis: | Catalytic chain transfer polymerization of benzyl methacrylate leads to a mixture of poly(benzyl methacrylate) macromonomers. Benzyl methacrylate dimer macromonomer has been isolated as a pure compound and used as a radical addition fragmentation chain transfer agent. This results in poly(methyl methacrylate) with both α and ω terminal benzyl methacrylate units. Catalytic hydrogenation of α,ω-benzyl methacrylate terminal poly(methyl methacrylate) results in evolution of toluene and formation of α,ω-dicarboxyl functional telechelic poly(methyl methacrylate). The products have been fully characterized by matrix-assisted laser desorption time-of-flight mass spectrometry in conjunction with 1H and 13C n.m.r. spectroscopy. |
