Synthesis of a series of novel terpolymers, consisting of two electron-donating monomers, viz. citronellol (optically active) and styrene, with one electron-accepting monomer, i.e. methyl methacrylate, using benzoyl peroxide as radical initiator and xylene as diluent at 80degreesC for 2 h has been extensively studied. The system follows ideal kinetics with an overall activation energy of 33 kJ mol(-1). The formation of the terpolymer is confirmed by the presence of peaks at 7-8 delta because of phenyl group, 3.4-4 delta because of methoxy group, and 7-7.7 delta because of alcoholic group in H-1 NMR spectrum of the terpolymer. Further, the bands at 2900 cm(-1), 1750 cm(-1), and 3400 cm(-1), observed in FTIR spectrum of terpolyrner, evidence the presence of phenyl, methoxy, and alcoholic group respectively. The monomer feed-terpolymer composition was determined by the Kelen-Tudos method. The values of reactivity ratios are r(1) (MMA) = 0.9 and r(2) (styrene + citronellol) = 0.02.
