摘要
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.
