Free radical copolymerization of styrene(St) and n-Butyl Methacrylate(BMA)was carried out with Benzoylperoxide(BPO) as the initiator in toluene in a batch reactor. The monomer reactivity ratios, r₁(St) and r₂(BMA) were determined by both the Kelen-Tudos method and the Fineman-Ross method : r₁=0.61(0.60), r₂=0.57(0.55). The rate constants of copolymerization, propagation and termination were determined. The ψ factor of the copolymer over all St compositions ranged from 0.46 to 0.91. The ψ factors of St-BMA copolymer increased with increasing St composition.
