The Study on Mathematical Simulation and Analysis of the Molecular Discrete System of the Sulfurated Eucommia Ulmoides Gum

In recent years, sulfurized eucommia ulmoides gum (SEUG) has been used and developed in many fields due to its good properties. The cross-linking degree is crucial the performance of SEUG. order explore effect on SEUG depth, this paper combines macroscopic microscopic techniques, molecular discrete system models EUG with different degrees are calculated by dynamics simulation, density solubility parameters EUG, glass transition temperature, radial distribution function mechanical property derived. results show that (1) suitable minimum polymerization N = 30; (2) a significant intramolecular SEUG, but it small intermolecular SEUG; (3) should be controlled between 40% 80% because properties namely bulk modulus, shear elastic Poisson’s ratio, Corsi pressure, best ones. Therefore, conclusions study provide theoretical basis for engineering practices.
