ABSTRACT:
Processes are described in which solution composition is monitored by extremely accurate measurements of index of refraction involving measurement of reflectivity from a glass-solution interface. A particularly useful application is the swelling operation in metallizing polymer surfaces where dimethylformamate-water solution is contacted with the polymer surface to produce the swelling. Accurate, continuous control of the solution composition is necessary to insure optimum amount of swelling.
