Abstract : Continuous and intermittent stress relaxation experiments were carried out on dicumyl peroxide cured cis-polybutadiene in vacuum at several temperatures. An extension of the two-network theory is proposed whereby the effectiveness of a crosslink at various extension ratios is experimentally defined. The effectiveness varies from unity at an extension ratio of unity to zero at very high extension ratios. (Author)
