ABSTRACT

In this work free-volume parameters needed for poly(styrene) – p-xylene-tetrahydrofuran coating and poly(methylmethacrylate) – tetrahydrofuran – ethylbenzene coatings were estimated by minimizing the difference between model predicted residual solvent and experimental residual solvent in binary coatings. Each ternary system needs two binary systems for example poly (styrene)-p-xylene-tetrahydrofuran system needs poly(styrene)-p-xylene and poly(styrene) – tetrahydrofuran.
