Polymerization of Methyl Methacrylate Initiated With Poly(formylstyrene)

Abstract

The polymerization of methyl methacrylate(MMA) initiated by poly(formylstyrene) (PFS) was carried out in p-dioxane at 85°C. The rate of polymerization was expressed by the following equation: Rp = const. [PFS]0.43[MMA]1.31. The polymerization proceeded homogeneously through a radical mechanism. The initiating ability of PFS was found to be larger than that of benzaldehyde indicating a macromolecular effect on the polymerization.

A novel and convenient method for synthesis of formylated polystyrene via oxidative scission from poly[(methoxymethyl)styrene] mediated by a nitroxyl radical

“…3 Furthermore, the polymerization of formylstyrene has been reported to lead to formation of gelled polymer and polymers with high polydispersity. 4 In the present paper, we describe a convenient preparative method for formylated polystyrene involving polymer modification via the oxidative scission of a benzyl ether moiety mediated by a nitroxyl radical. 4-Methoxy-2,2,6,6-tetramethylpiperidine-l-oxyl (2), a nitroxyl radical which is well-known as a spin trapping or labeling agent, forms the following reversible redox system.…”
