摘要：
The equation for equilibrium melting point depression in a polymer mixture is derived based on the equation of state theory. For two miscible blend systems poly(methyl methacrylate)/poly(vinylidene fluoride) and poly(vinyl chloride)/poly(ethylene oxide), the newly derived equation is tested. The interaction parameter X12 between two polymers in a mixture can be estimated from this equation. When the estimated interaction parameter is converted to Flory-Huggins interaction parameter chi via the equation of state theory, the composition dependence of chi can be properly predicted. The equation for nonequilibrium melting point depression is also suggested; however, the interaction parameter in a polymer mixture cannot be precisely estimated without the correct consideration of a morphological effect on the nonequilibrium melting point depression.
