Abstract Four binary polymer -solvent systems, poly(styrene)-tetrahydrofuran, poly(styrene) - p-xylene, poly(methyl methacrylate) - ethylbenzene and poly(methyl methacrylate) - tetrahydrofuran, systems have been studied. It has been observed that thicker coatings will retain a higher amount of the residual solvent as compared to thinner coatings. In the case of poly(styrene)-tetrahydrofuran coating residual solvent remaining within the coatings were 9.09% and 4.74% for the coatings of the thicknesses of 967 micron and 559 micron, respectively. Similar trends were also observed in the case of poly(methyl methacrylate)-ethylbenzene, poly(methyl methacrylate)-tetrahydrofuran, and poly(styrene)-p-xylene systems.

Microscopical observations of films made up of two incompatible polymers may provide useful insights into the unusual properties of many polymer blends. In the present study an attempt has been made to determine the factors which control the sizes and shapes of the phases present in solution-cast, two-polymer films. The variables included the ratio of the two polymers, the concentration of the solution from which the films were prepared, and the type of solvent used.The polymers studied included poly(vinyl acetate), a copolymer containing 85% poly(vinyl chloride) and 15% poly(vinyl acetate), poly(methyl methacrylate, and polystyrene. These will be abbreviated PVAc, PVC copolymer, PMMA, and PS respectively. The solvents included methyl ethyl ketone (MEK), toluene, benzene, and chloroform and the solution concentrations were varied from 0.2 to 1.0 per cent solids by weight.
