The availability of cyclopentene as a petrochemical by-product served as the driving force for the development of polypentenamer. Cyclopentene will undergo ROMP, though because of minimal ring strain, single-pass complete conversions are difficult to obtain.

Cyclopentene is a cyclic alkene with the molecular formula C₅H₈. It is a key structural component in organic chemistry, with important applications in the context of calculating the degree of unsaturation, olefin metathesis polymerization, and intramolecular olefin metathesis.
