POLYMERIZATION IN A MAGNETIC-FIELD .10. SOLVENT EFFECT IN POLY(METHYLMETHACRYLATE) SYNTHESIS

The effect of a continuous external magnetic field on the free radical polymerization of methyl methacrylate was studied with respect to som e properties of the solvents used in the reaction. The studies were pe rformed through dilatometric technique in and out a magnetic field of 0.25 T. Ten different solvents were used to underline the dependence b etween the magnetic field presence, the reaction medium, and the devel opment of the polymerization process. The intervened magnetokinetic ef fects are attributed to the changes in the multiplicity of the radical pairs owing to the magnetic field influence. There is an interdepende nce among the viscosity and molar polarization of the solvents and the magnetic field effect. (C) 1996 John Wiley & Sons, Inc.
