Abstract
Methods of preparing oligomers including heating a mixture of an amount of a functionalized cycloalkene, an amount of a chain transfer agent, a phosphite ester, and a catalyst, a degree of polymerization of the oligomers controllable by a molar ratio of the amount of the functionalized cycloalkene to the amount of the chain transfer agent, are provided herein. Methods of preparing polymers including heating the oligomers and a second amount of the functionalized cycloalkene, a phosphite ester, and a catalyst are further provided. Compositions of oligomers and functionalized cycloalkenes are further provided.
