The bulk free radical copolymerization of n ‐butyl methacrylate (BMA) and D ‐limonene is carried out at 80 °C using benzoyl peroxide (BPO) as initiator. Low conversion experiments are conducted to estimate the copolymer reactivity ratios while full conversion runs are performed to verify the estimates and to achieve high monomer conversions. Reactivity ratios of r 1 = 6.0957 and r 2 = 0.0459 (1 = BMA, 2 = D ‐limonene) are obtained using a nonlinear, error‐in‐variables method with the RREVM computer program. Full conversions and reasonably high molecular weights are achieved at high BMA feed concentrations. Achieving high conversion is limited by a degradative chain transfer mechanism due to the D ‐limonene.
