This article briefly reviews the theories, experimental methods and influencing factors on the compatibility of polymer blends. Theories include thermodynamic criteria, Scott theory and the state equation theory developed in recent years. The experimental methods involve electron and optical microscopy, light scattering, X-ray scattering, neutron scattering, glass transition temperature, melting point reduction, calorimetry, reversed-phase gas chromatography, infrared absorption spectroscopy, fluorescence spectroscopy and nuclear magnetic resonance Other methods. The effects of intermolecular forces, molecular weights, ambient temperature and pressure, and compatibilizers on the compatibility between polymers were summarized.
