    • Abstract


      Homopolymerization of methyl methacrylate (MMA) was carried out in the presence of triphenylstibonium 1,2,3,4-tetraphenyl-cyclopentadienylide as an initiator in dioxane at 65°C±0·l°C. The system follows non-ideal radical kinetics (Rp ∝ [M]1·4 [I]0·44@#@) due to primary radical termination as well as degradative chain-transfer reaction. The overall activation energy and average value ofk2p/kt were 64 kJmol−1 and 0.173 × 10−3 1 mol−1 s−1 respectively
