In the present paper, we report results obtained analyzing the swelling behavior of a composite system prepared from vulcanizing mixtures of cis ‐polybutadiene and methacrylic acid with different amounts of acid. Two solvents were used as swelling agents, decalin and the N,N‐dimethylformamide. The structural data, given by low‐angle x‐ray diffusion spectra, were used to interpret the mechanical behavior described in terms of the Mooney‐Rivlin equation and hysteresis loops. Structural and mechanical data give information about the swelling mechanism of the solvents and about the problem of the experimental deviations from the Gaussian theory of rubber elasticity.
