Preparation and physical studies of polyarylene vinylene copolymers and their analogous blends

Roberto Ma. S Gregorius, University of Massachusetts Amherst

Abstract

The synthesis and physical characterization of a series of poly(p-phenylene vinylene-co-2,5-thienylene vinylene) (PPV-co-PTV) were reported. The synthetic route used was a variation on the Wessling route to poly(p-phenylene vinylene) which involved a precursor polymer. The copolymeric nature of the materials produced were investigated by IR analyses of the trans-vinylene absorption of these systems. The results of the attempts to produce other polyarylene vinylene (PAV) copolymers were also reported. The conductivity and orientational properties of PPV-co-PTV in comparison with those of the blends of poly(p-phenylene vinylene) (PPV) and poly(2,5-thienylene vinylene) (PTV) were investigated. The interrelation of the PTV contents, sequence distributions, conductivities, draw ratios, morphology and order parameters for the copolymers and blends were discussed. The effects due to the random copolymeric nature of PPV-co-PTV were emphasized.
