Abstract

The article presents the study results on the 18 networks of four kinds of rubbers: NR, SBR, NBR and PDMS on the relation between the networks, presented by sous-chains Mc, and the elasticity modulus. Two techniques used are swelling and tensile modulus. The results clearly indicates that the relation between network structure and the rubber elasticity is linear and doesn't depend on the nature and the structure of the vulcanizates.
