This research will be divided into three portions to study on the mass transport of cosolvent in poly(methyl methacrylate)、the crystallization condition of the substrates vs. the properties of the crystallization specimen. The experimental results indicate that the mass transport of this two cosolvent in poly(methyl methacrylate) (PMMA) is an endothermic process. The two saline have different influence on the diffusion coefficient for CaseⅠ, the diffusion velocity for CaseⅡ, the activation energy of diffusion coefficient in CaseⅠtransport and the activation energy of diffusion velocity for CaseⅡ. The transmittance of the specimen with calcium carbonate crystallization varies with the UV and visible wavelength shows that the absorption zone and cut-off wavelength has blue shift, but as for the specimen with iron carbonate crystallization it has red shift. The FTIR spectrum of the specimen with calcium carbonate crystallization didn’t have obvious change, but the FTIR spectrum of the specimen with iron carbonate crystallization shows the new absorption peak at 1405.06cm-1、3053.78 cm-1 and 3144.58 cm-1. In addition, the glass transition temperature (Tg) of the specimen with iron carbonate crystallization will rise as the increase of mass transport temperature and concentration.
