Notes:
Ferrocenylmethyl methacrylate (FMMA) was copolymerized with styrene (St), methyl methacrylate (MMA), and ethyl acrylate (EA) in benzene solution at 25°C by γ radiation. The reactions proceeded by a free radical mechanism, and monomer reactivity ratios were derived by the Tidwell-Mortimer method for St(M1)-FMMA(M2), r1 = 0.35 and r2 = 0.46; for MMA(M1-FMMA)(M2), r1 = 0.85 and r2 = 1.36; for EA(M1)-FMMA(M2), r1 = 0.36 and r2 = 3.03. The Q and e values of FMMA determined from copolymerization with St were 0.97 and 0.55, respectively. Terpolymerization of a MMA-FMMA-EA system based on the Alfrey-Goldfinger equations was studied. This is a typical terpolymerization system in which reactivities of the monomers obey the Q-e scheme. Comparing the results obtained here with those previously reported for other monomers, we concluded that FMMA is one of the most highly reactive monomers among alkyl methacrylates.
