The obtained polymers were analyzed by spectral and thermal analyses.Īcrylates containing polymers have potential applications in industries like textile, surface coating, automotive, aerospace, biomedical to optics and microelectronics, etc. The results obtained from this investigation were used for inferring the radical mechanism of phase-transfer-catalyzed polymerization. The Ea value supports the reactivity of acrylates. The activation energy (Ea) and other thermodynamic parameters were calculated. Polymerization reactivity of methyl and ethyl methacrylate under PTC conditions was studied by various parameters. It extracts the reactive radical anion from aqueous phase and transfers to the organic phase where acrylates were polymerized. Without addition of PTC, polymerization did not occur this indicates that catalyst plays the pivotal role on initiation of polymerization. PTC has myriads of applications in the synthesis of various organic and polymeric materials because of its fast reaction and high yield in short period of time. Polymerization follows first-order kinetics with respect to monomer and half-order with respect to catalyst and initiator, respectively. Polymer yield was increased with increasing molar concentrations of monomer, initiator, catalyst and temperature. Methyl and ethyl methacrylate was polymerized in heterogeneous system with the help of newly synthesized multi-site phase-transfer catalyst and using water-soluble initiator at 60 ± 1 ☌ under unstirred inert atmospheric condition.
