The polymerization rates were very low. Depending on the particular monomer, ZIEGLER and/or cationic catalysts were effective. Cyclopentene polymerizes both by double bond opening (producing enchained cyclopentane rings) and by ring opening to give <jats:italic>cis</jats:italic> and <jats:italic>trans</jats:italic> polypentenamers. The resulting polymers are partially crystalline and have birefringence melting points between 120 and 150°C. The 3‐methylcyclopentene and 3‐methylcyclohexene monomers polymerize (at least partly) by 1,3‐addition following a 3,2‐hydride shift. The 3‐methylcyclohexene polymers are also partly crystalline and have birefringence melting points between 200 and 250°C. Little ring‐opening polymerization of the methylcycloolefins occurs. Polymerization mechanisms are discussed.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383388846014992898","@type":"Researcher","foaf:name":[{"@value":"J.
