Molecular relaxations in the glassy state of polymers with unsaturated backbone chains and their hydrogenated derivatives

Summary

A study of the dynamic mechanical behaviour of poly(propene-alt-1, 4-butadiene), poly(styrene-b-isoprene) SIS triblock, and their hydrogenated derivatives has been carried out using torsional braid and rheovibron techniques. It was found that the existence of low temperature damping processes (120–160K/1Hz) depends on the molecular structure, particularly on the geometric isomerism of the double bond. Simple ring analogues have been used as models to elucidate the molecular mechanisms underlying these relaxation processes.
