Abstract
Ce(IV) INITIATED POLYMERISATION OF ACRYLAMIDE IN PRESENCE OF β- CYCLODEXTRIN
A. Kavitha* and M.C. Duraimanickam
ABSTRACT
The kinetics of polymerization of acrylamide initiated by Ce(IV) – Lactic acid redox system in the presence of ?-cyclodextrin (?-CD) have been studied for the temperature 30oC and 35oC in dilute sulphuric acid medium. The rate of polymerization Rp(obs) as well as the rate of Ce(IV) consumption, Rce, were found under various concentration of monomer (acrylamide), lactic acid(reductant), Ce(IV)(oxidant), and H+ (acid), etc. both for the temperature 30oC and 35oC in the presence of ?-cyclodextrin (?-CD) and in the absence of ?-CD and the results were compared. As the temperature increases rate of polymerization Rp increases. Due to the presence of cavity in ?-cyclodextrin the rate of polymerization decreases.The cavity enhances the complexation of oxidant, reductant and monomer,etc.
