Key Points

To determine whether catalyst selection allows the direct incorporation of diazirine carbene precursors into polyolefin backbones via ring-opening metathesis polymerization while maintaining functional group reactivity.
Applied catalyst-tuned ring-opening metathesis polymerization (ROMP) to embed diazirine-based carbene precursors into polyolefin backbones.
Selected specific olefin metathesis catalysts to prevent premature degradation of the reactive diazirine groups during polymer synthesis.
Direct ROMP successfully integrated diazirine units along polyolefin backbones while fully preserving their latent carbene reactivity.
The resulting functionalized polyolefins served as effective macromolecular crosslinking agents for hydrocarbon polymers.
