高分子构象弹性理论

Conformational Elasticity Theory of Polymers

本研究提出了一个能够预报高分子形变中熵项与内能项分别的贡献以及应力应变行为的构象弹性理论。它克服了高斯链理论不能从分子结构上说明大形变的弱点，首次预报了天然橡胶形变中内能的贡献为１３％。

The theory proposed here can predict the behavior and the contributions of the energy term and the entropy term during the elongation of polymers.This proves that the change in chain conformations is physically able to make the upward curvature at larger elongation.The energy contribution of 13% calculated in the present study is coincided with the observation for natural rubber.
