| Abstract: | From light scattering measurements the coil-globule transition has been observed for poly(methyl methacrylate) in the mixed solvent water+tert-butyl alcohol with molecular weight Mw=2.38×106. Since the phase separation occurred very slowly for this system, the mean square radius of gyration 〈s2〉 and the second virial coefficient A2 were determined reliably even far below the phase-separation temperature. A comparison of the observed 〈s2〉 with a theory for a contracted coil confirmed the coil-globule transition. The observed second virial coefficient had a minimum in the temperature region where 〈s2〉 approaches the value for the globule state. |
