| Abstract: | The tacticities of poly(glycidyl methacrylate) prepared by radical polymerization at temperatures in the range from ?78 to 60°C in several solvents or in bulk are described. The redox system diisopropylperoxy dicarbonate/dimethylaniline was found to polymerize this monomer effectively even at low temperature. The tacticities were determined by NMR spectroscopy. The difference of entropy Δ(ΔS ) and enthalpy Δ(ΔH ) of activation between isotactic and syndiotactic propagations were calculated. The values of Δ(ΔH ) were found not to be affected essentially by polymerization conditions and to be slightly larger than that of methyl methacrylate polymerization. |
