Abstract

In this study, superswelling behaviour of two different cross-linked polymer of 3,4-epoxycyclohexylmethyl-3',4'-epoxycyclohexane-carboxylate (EEC) monomer was investigated. The cross-linked polymer of EEC i.e., (PEEC) and EEC with cyclohexene end-functional polystyrene macromonomer (PEEC-co-PSt) were prepared by photoinitiated cationic polymerization using diphenyliodonium salt (PhI2+). The per cent swelling, equilibrium swelling, initial rate of swelling, swelling rate of constant and diffusion constant values were evaluated for PEEC and PEEC-co-PSt gel systems in dimethyl sulfoxide. PEEC and PEEC-co-PSt gels were swollen in the range 878-999% in DMSO. The adsorption of procion blue HERD dye onto PEEC and PEEC-co-PSt in DMSO solution was investigated. The equilibrium adsorption data on reactive dye on PEEC and PEEC-co-PSt were analyzed by Langmuir and Freundlich models. The maximum adsorption capacity (q(m)) has been found to be 556 mg/g for PEEC and 714 mg/g for PEEC-co-PSt gels.
