Structure–property relationships in crosslinked networks from cis-1,4-polybutadiene and methacrylic acid. Preliminary results

In this paper we report preliminary results obtained analyzing structural data and mechanical properties of a composite system prepared vulcanizing mixtures of cis polybutadiene and methacrylic acid with different acid amount. The structure was investigated by the small angle x-ray scattering, while the physicomechanical properties were analyzed carrying out stress and birefringence measurements as function of the strain at constant temperature.
