Kinetics and mechanism of the radical copolymerization of 4‐vinyl pyridine with methyl acrylate initiated by p‐acetylbenzylidene triphenylarsonium ylide

Abstract

The free-radical copolymerization of 4-vinyl pyridine (4-VP) with methyl acrylate (MA) initiated by pacetylbenzylidene triphenylarsonium ylide at 60 AE 0.1 C with dioxane as an inert solvent yielded random copolymers. , respectively. The reactivity ratios calculated with the Kelen-Tü dos method were 0.14 AE 0.0075 for 4-VP and 0.56 AE 0.0078 for MA. The copolymers were characterized with Fourier transform infrared, proton nuclear magnetic resonance, differential scanning calorimetry, and electron spin resonance methods.
