Vinyl cyclohexane (VCH) is a valuable monomer in polymer science, prized for its ability to polymerize and copolymerize, producing materials with unique properties such as enhanced thermal stability, mechanical strength, and optical clarity. As a monomer, VCH contains a reactive vinyl group that can participate in addition polymerization, forming poly(vinylcyclohexane) (PVCH) . Research on VCH focuses on its polymerization behavior, including factors that affect its reactivity and the molecular weight of the resulting polymers, as well as its ability to copolymerize with other monomers to create polymers with tailored properties .

A key advantage of VCH-based polymers, particularly PVCH, is their significantly enhanced thermal stability compared to polystyrene. Thermogravimetric analysis (TGA) confirms that PVCH possesses good thermal stability with an initial decomposition temperature exceeding 345°C, a substantial improvement over polystyrene, whose thermal decomposition onset typically occurs at approximately 280-300°C . This enhanced stability is attributed to the fully saturated cycloaliphatic backbone, which lacks the thermally labile benzylic C-H bonds present in polystyrene . Additionally, PVCH exhibits a high glass transition temperature (Tg) of approximately 146°C, which is about 40°C higher than that of polystyrene . The combination of high Tg and elevated decomposition temperature makes PVCH-based materials particularly well-suited for applications requiring sustained performance across a broad thermal operating window .

VCH is also studied for its use as a co-monomer in copolymerization reactions. Researchers have investigated its use in copolymers with other alkenes, such as ethene and propene, using metallocene catalysts, to understand the factors influencing copolymer properties . Isota
