Description

5-Isopropenylnorborn-2-Ene CAS NO 13234-21-4 is a specialized, high-purity bicyclic olefin monomer with a reactive norbornene backbone and an isopropenyl substituent. This unique structure makes it a valuable intermediate for advanced polymer synthesis, particularly in the production of specialty resins, functionalized polymers, and materials requiring tailored thermal and mechanical properties. It is essential for R&D and manufacturing in sectors such as advanced adhesives, photoresists, and performance elastomers where precise molecular architecture is critical.

Application

• Ring-Opening Metathesis Polymerization (ROMP) Monomer: A key building block for synthesizing polynorbornene-based polymers with controlled architectures.
• Specialty Resin & Adhesive Formulations: Used to create high-performance, thermally stable adhesives and sealants for demanding industrial applications.
• Photoresist & Electronic Chemicals: Serves as a precursor in the development of advanced photoresists and dielectric materials for the semiconductor industry.
• Functional Polymer & Elastomer Synthesis: Enables the introduction of reactive sites into polymer chains for cross-linking or further chemical modification.
• Organic Synthesis Intermediate: Utilized in Diels-Alder and other cycloaddition reactions to construct complex polycyclic structures in pharmaceutical and agrochemical research.
• Cross-linking Agent: Acts as a co-monomer to introduce cross-linking points, enhancing the durability and chemical resistance of final polymer products.
