Abstract

The χ-parameter in the Flory-Huggins equation of methyl methacrylate and polymethyl methacrylate was determined to be χ=0.33, from the observation of vapour pressure of the reaction mixture in a pilot scale reactor for continuous bulk polymerization of methyl methacrylate. The monomer content of the polymer solution flushed from the pressurized heat exchanger to the vent extruder almost agreed with the equilibrium concentration calculated from the Flory-Huggins equation. The monomer content of the resulting pellet (0.150.37%) was far from the equilibrium concentration (0.02%) at the front vent, suggesting that the monomer content must be decreased by improvement of the screw design.
