Abstract

Abstract: Conformational elasticity theory of chain molecule" proposed by our group was used to explore the contribution of internal energy to elastic force(f_e/ f). 1,4 Polybutadiene(cis and tran) were studied. The calculated f_e/ f for cis polymer is consistent with experimental data, while a little difference for the trans polymer, which needs more experimental data to support. The results also show that f_e/ f is dependent on chemical structure and strain.

Key words: Internal energy, Conformational elasticity theory, Polybutadiene
