| Abstract: | Glass transition temperatures are reported for narrow MWD PMMA for a range of MW, where the polymer is (a) free of methanol, and (b) equilibrated with methanol. The relationship between the glass transition temperature and MW is discussed in terms of current empirical and thermodynamic theories. |
