Abstract EN

This research is addressing the effect of different ferrocene concentration (0.00, 2.15x10-3, 4.30x10-3, 8.60x10-3, and 12.9x10-3) on the bulk free radical polymerization of methyl methacrylate monomer in benzene using benzoyl peroxide as initiator.

The polymerization was conducted at 60º C under free oxygen atmosphere.

The resulting polymers were characterized by FTIR.

The results were compared with the presence and absence of ferrocene at 10% conversion.

The %conversion was 3.04% with no ferrocene present in the polymerization medium and its increase to 9.06 with a first lowest ferrocene concentration added, i.e.

2.15 x10-3mol/l.

This was positively reflected on the poly(methyl methacrylate) molecular weight measured by viscosity technique, especially in the presence of ferrocene.
