Collection: Cyclic Olefin Monomers

Cyclic Olefin Monomers — brings together cyclic and bicyclic olefin compounds such as norbornene, vinyl-substituted cyclohexene, and unsaturated cyclic carbonates that carry reactive double bonds within the ring structure. This group serves as monomer units or comonomers in various chain-growth polymerization and ring-opening reactions.

Cyclic Olefin Monomers are used by polymer researchers to prepare cyclic olefin copolymers (COC) and high-durability optical resins, including through ROMP (ring-opening metathesis polymerization) and free radical polymerization. Monomers such as vinylcyclohexene and norbornene derivatives are also used as comonomers that modify thermal and mechanical properties in electrolyte materials, while vinylene carbonate serves as an electrolyte additive in battery research.

Example products in this collection: TCI A0005 208-96-8 Acenaphthylene, TCI C0503 111-78-4 1,5-Cyclooctadiene [stabilized with Octadecyl 3-(3',5'-Di-tert-butyl-4'-hydroxyphenyl)propionate], TCI V0062 3048-64-4 5-Vinylbicyclo[221]hept-2-ene (stabilized with BHT), TCI C0506 931-88-4 Cyclooctene, TCI V0023 100-40-3 4-Vinyl-1-cyclohexene (stabilized with BHT), TCI C0511 142-29-0 Cyclopentene, TCI V0015 872-36-6 Vinylene Carbonate (stabilized with BHT), TCI C0688 628-92-2 Cycloheptene.

Please note the stability of these compounds, which generally requires added stabilizers such as BHT to prevent premature polymerization, as well as the isomer mixtures in some bicyclic products that may affect the uniformity of polymerization results. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
