Abstract

This study uses Raman spectroscopy to quantitate the amount of polymer in solution, in particular poly(ethylene glycol) dissolved in chloroform. For various chain lengths and polymer weight fraction ranges, it is shown that the ratios of peak intensities in the C-H stretching region may be used to quantitate polymer weight fraction with about 1% uncertainty. For low polymer weight fraction ranges (0-10%), the relationship between Raman intensity and polymer weight fraction is essentially linear, while at higher ranges (0-50%) the intensity follows a nonlinear function derived from basic concentration relationships and indicates a universal scaling with polymer chain length.
