  • Polymeric materials derived from ring-opening polymerization of 1,5-cyclooctadiene
    Patent number: 3932373
    Abstract: These polymers are characterized as having a structure of polyalkenemers in which the double bonds are of the cis and trans vinyl type configuration and no double bonds are of the 1,2 type configuration. The polymers are further characterized by repeating units of--CH.sub.2 --CH=CH--CH.sub.2 --CH.sub.2 --CH=CH--CH.sub.2 --in which at least 75 percent of the vinyl double bonds are of the cis type configuration and none of the double bonds are of the 1,2-type configuration.
