N. Daniel et Ak. Srivastava, Radical polymerization of vinyl acetate using p-acetylbenzylidene triphenylarsonium ylide as an initiator, EUR POLYM J, 37(11), 2001, pp. 2313-2318
p-Acetylbenzylidene triphenylarsonium ylide initiated radical polymerizatio
n of vinyl acetate in dioxane has been carried out at 65 +/- 0.1 degreesC i
n polymerization tubes for 8 h under nitrogen. The initiator and monomer ex
ponents are 0.44 and 1.5 respectively. The overall activation energy and va
lue of k(p)(2)/k(t) are 35 kJ mol(-1) and 6.06 x 10(-3) 1 mol(-1) s(-1) res
pectively. The ylide is believed to dissociate to generate phenyl radicals
which initiate the radical polymerization of vinyl acetate. (C) 2001 Elsevi
