The tensile and dynamic mechanical properties of poly(norbornene), prepared through ring‐opening polymerization, were studied. Tensile strength and extensibility increased, while Young's modulus decreased with increasing molecular weight and with increasing content of trans relative to cis unsaturation. The damping factor Delta; was dependent on molecular weight only for the lower molecular weight samples. The out‐of‐phase modulus E ″ and the damping factor decreased as the trans/cis ratio increased.
