The bulk free radical copolymerization of d‐limonene (Lim) with n ‐butyl acrylate (BA) was carried out at 80 °C using benzoyl peroxide as initiator. Low conversion experiments were run to estimate the copolymer reactivity ratios as r BA = 6.07 and r Lim = 0.0067. High conversion experiments were then conducted to validate the reactivity ratios for prediction of cumulative copolymer composition. The presence of allylic hydrogen in d‐limonene caused a notable degradative chain transfer reaction which greatly impeded polymerization. Increasing d‐limonene fractions in the copolymer resulted in a decrease in final conversion and molecular weight, and an increase in glass transition temperature.
