For measurements of the refractive index increment of polymer solutions, with a standard Jena interference refractometer, certain modifications of the measuring cell have been proposed. At room temperature, a simple closure for the cell protects the solutions from evaporation, contamination or loss
Differential refractometry has been used to obtain accurate values of the specific refractive index increments for the following polymers in several solvents: polystyrene, poly(methyl methacrylate), poly(4-vinyl pyridine), block copolymers of styrene with methyl methacrylate and of styrene with 4-vi
