Abstract

Free radical copolymerization of an acyclic monoterpenoid linalool (LIN) and methyl methacrylate (MMA) in dioxan was carried out in dilatometer under an inert atmosphere of nitrogen for 90 min at 60 ± 1°C by using diphenyl selenonium 2,3,4,5‐tetraphenylcyclopentadienylide (selenonium ylide) as an initiator. The kinetic expression of the reaction is R~p~ ∝ [ylide]^0.5^[MMA]^1.0^[LIN]^1.0^. The activation energy of copolymerization was estimated to be 43.7 kJ mol^−1^. The formation of a functional copolymer is evidenced by spectral analysis. The copolymer was characterized by FTIR, ^1^H NMR, ^13^C NMR, DSC, and TGA analysis. © 2010 Wiley Periodicals, Inc.
