The paper addresses the application of a sessile drop method for the study of surface quality of thermoplastic polymer materials—polystyrene and polymethyl methacrylate—upon edge cutting machining. A correlation has been found between the thermal-physical state of their surface layer and the surface wettability. The method is demonstrated to be suitable for the assessment of thermodynamic stability of the surface layer structure of polymers during finishing operations in the manufacture of optical products.
