Abstract Naturally occurring bulky terpenes, such as (+)-and (–)-limonene and (–)-β-pinene, were quantitatively copolymerized with maleimide (MI) derivatives (ie, phenyl-, cyclohexyl-, ethyl-, and unsubstituted-MI) in PhC (CF 3) 2 OH solvent via selective 1: 2-alternating propagation governed by the penultimate effect, which resulted in 1: 2-sequence regulated polymers with relatively high glass transition temperatures and optical activities.
