Polymer-Analog Reactions of Polyvinyl Alcohol under the Action of Microwave Radiation

摘要

Effect of microwave radiation on the polymer-analog reaction of polyvinyl alcohol with low molecular ketone, cyclohexanone, was studied. It is shown that using the energy of this radiation permits to increase considerably the rate of formation of polyketal as compared to the thermal action. It is found that the process of formation of final product may be governed by the nature of solvent. In this case not only the change in solubility must be considered, but the competing absorption of microwave energy by the solvent as well.
