We apply molecular dynamics (MD) simulations to investigate crystal nucleation in incompatible polymer blends under deep supercooling conditions. Simulations of isothermal nucleation are performed for phase-separated blends with different degrees of incompatibility. In weakly segregated blends, slow and incompatible chains in crystallizable polymer domains can significantly hinder the crystal nucleation and growth. When a crystallizable polymer is blended with a more mobile species in interfacial regions, enhanced molecular mobility leads to the fast growth of crystalline order. However, the incubation time remains the same as that in pure samples. By inducing anisotropic alignment near the interfaces of strongly segregated blends, phase separation also promotes crystalline order to grow near interfaces between different polymer domains.

To study the influence of fining temperature on glass qualities, different fining temperatures from 1400°C to 1500°C were used to prepare a series soda-lime-silica glass with identical chemical compositions. Infrared spectroscopy was used to determine the water content of glass, general analyzer of melt physical properties was used to study the viscosity and surface tension change of glass melt, microscope was carried out find glass bubbles, wet chemical analyses were used to determine the Fe2+/(Fe2++Fe3+) ratio. The results show that, generally, with the increase of fining temperature, the glass melt’s water content, bubbles number and Fe2+/(Fe2++Fe3+) ratio increase, viscosity decreases. Particularly, when the fining temperature is 1450°C, the glass has lowest water content, bubbles number, Fe2+/(Fe2++Fe3+) ratio, and viscosity, and its surface tension is largest. Among all tested fining temperature, 1450°C is the optimal fining temperature.
