Abstract
Interpenetrating polymer network (IPN) based on poly(styrene) and poly(citronellol-alt-methylmethacrylate) have been synthesized by using benzoyl peroxide as initiator and divinyl benzene as crosslinking agent, in xylene under an inert atmosphere of nitrogen. The scanning electron microscopy reveals a characteristic two phase morphology of linear polymer dispersed in the matrix of copolymer. The properties like percentage swelling, average molecular weight between crosslinks (Mc), are direct function of [copolymer] and initiator [benzoyl peroxide] whereas inverse function of concentration of monomer (styrene) and crosslinker (divinyl benzene). The differential scanning calorimetry gives two values of glass transition temperature at 64.09 °C and 159.79 °C. The value of activation energy, calculated from thermogravimetric analysis, is 20 kJ mol-1.
