inhibitor are mixed in a reactor followed by heating while stirring the water generated in the esterification reaction is entrained by an azeotropic distillation with the azeotropic solvent out of the reactor followed by cooling the reaction product after completion of dehydration in succession the reaction product is washed with an alkaline water solution and an inorganic salt water solution followed by removing the azeotropic solvent under the reduced pressure on dehydration and washing with water the polymerizationinhibitor may be further added the residual product in the reactor is the present polycarbonate meth acrylate composition can be optionally applied with or without refining for example by absorption with activated carbon or activated alumina etc specific preferable examples of the esterification reaction catalyst include sulfuric acid hydrochloric acid benzene sulfonic acid p toluene sulfonic acid etc specific preferable examples of the polymerization inhibitor include hydroquinone p benzoquinone p tert butylcatechol diphenylamine thiosemicarbazide sulfur phenothiazine hydroquinone monomethylether etc the azeotropic solvent for dehydration is preferably stable chemically in the reaction mixture insoluble in water and capable of forming an azeotropic mixture with water specific preferable examples of azeotropic solvents include for example cyclohexane benzene toluene n hexane trichloroethylene isopropylether etc the dehydration temperatures are preferably in the range of from 80 to 120 u00b0 c depending upon the amount and the kind of.
