溶解度参数是物质分子间作用能的一种量度,它是表征分子间相互作用的参数之一,所以凡和分子间相互作用有关的某些物理量,如状态方程常数及临界常数、热膨胀系数及压缩系数、表面张力、折射率、介电常数和无定形高分子的玻璃化温度等都和溶解度参数之间存在着一定关系。在这一讲中我们将分别介绍这些物理量和溶解度参数之间的关系。 Solubility parameter is a measure of the interaction energy between molecules. It is one of the parameters that characterize the interaction between molecules. Therefore, some physical quantities related to the interaction between molecules, such as the equation of state equation, the critical constant, the thermal expansion coefficient and the compression Coefficients, surface tension, refractive index, dielectric constant and glass transition temperature of amorphous polymers are all related to solubility parameters. In this talk we will describe separately the relationship between these physical quantities and the solubility parameters.
