Cyclohexene polymerization

Web5.5.1 Cyclo Olefin Copolymer Manufacture. Cyclo olefin copolymers are manufactured by the copolymerization of a cyclic olefin (e.g., cyclopentene, norbornene) with an olefin like ethylene or propylene. The reaction of polymerizing a cyclo olefin resulting in a polymer is known as ring opening polymerization (ROMP). WebCyclopentene is a chemical compound with the formula (CH2)3(CH)2. It is a colorless liquid with a petrol -like odor. It has few applications, and thus is mainly used as a minor component of gasoline, present in concentrations of less than 1%. [1] [2] It is one of the principal cycloalkenes .
