The solidification process of mixtures of glycerol and 1

6-hexanediol with three mole ratios are carried out using molecular dynamics method.Self-diffusion coefficient and the specific volume method are used to calculate glass transition temperature separately

and the results are in good agreement with the experimental data.The self-diffusion coefficients of glycerol and 1

6-hexanediol hydroxy in mixtures are less than that of glycerol and 1

6-hexanediol hydroxyl.The first peak values of radial distribution function of glycerol and 1

6-hexanediol hydroxy in the mixture are higher than that of pure glycerol or pure 1

6-hexanediol hydroxy.As the temperature decreases

the radius of gyration is shorter

smaller bond lengths appear more

and bond angles change little.
