The kinetics of methylacrylate (MA) polymerization initiated by Ce(IV) – Lactic acid redox system in the presence of β-cyclodextrin (β-CD) in aqueous sulphuric acid medium have been studied for the temperature 30 oC and 35 oC. The rate of polymerization Rp(obs) as well as the rate of Ce(IV) consumption, RCe, were found under various concentration of MA, Ce(IV), H+ and β- CD. Polymerization was done in both presence and absence of β-CD, and the results were compared. The β-CD complexation of oxidant and monomer decreases the rate of polymerization due to its cavity.
