Crystal Modifications and Thermal Behavior of Poly(<scp>l</scp>-lactic acid) Revealed by Infrared Spectroscopy

Recently, we reported the isothermal crystallization behaviors of poly(l-lactic acid) (PLLA) from the melt and glassy states, respectively [J. Phys. Chem. B 2004, 108, 11514; Macromolecules 2004, 37, 6433]. Surprisingly, the quite different infrared (IR) spectral evolutions occur in the two crystall... View More
