Abstract
Static and dynamic properties of polymer solutions have recently been investigated by laser light scattering.1 The concentrations studied have ranged from the very dilute to the semi-dilute and concentrated regions. In our case, we have chosen to characterize polystyrene (NBS 705 standard, Mw = 179,300, Mw/Mn = 1.07) dissolved in methyl acetate. In this system, the upper and lower critical solution temperatures differ by only ~125°C and the theta temperatures by only ~70°C.2,3 Consequently, one can monitor the change in quality of the solvent over a range of temperatures which are experimentally accessible.
