CHEMICAL STRUCTURE DEPENDENCE OF THE INTERNAL ENERGY CONTRIBUTION IN RUBBER ELASTICITY*

Revised Date: 23 May 2001

Conformational elasticity theory recently developed has been used to explore the internal energy contribution tothe elastic force fe/f as a function of strain for poly(cis-1,4-isoprene) and poly(trans-1, 4-isoprene). Calculated fe/f values arein good agreement with those obtained experimentally. Results show that behavior of fe/f is mainly contributed by chemicalstructure, or intramolecular interaction, supporting the experimental observations, and that the internal energy contribution is strain dependent.
