Polymerization studies on methyl and ethyl α‐fluoromethylacrylate

Abstract
Ethyl α‐fluoromethylacrylate was prepared from ethyl α‐chloromethylacrylate by reaction with potassium fluoride in sulfolane. The methyl ester was prepared by transesterification. The ethyl ester was found to be unexpectedly quite toxic. Homopolymers and copolymers of both monomers were found to have lower softening temperatures than polymers from the corresponding methacrylate monomers. Reactivity ratios were determined for ethyl α‐fluoromethylacrylate (M2) with styrene (r1= 0.34,r2= 0.09) and with methylmethacrylate (r1= 1.05,r2= 0.51).
