Abstract

The nature of the “peculiarly strong” interaction between the poly( l -lactide) (PLLA) and poly( d -lactide) (PDLA) chains was investigated by real time infrared spectroscopy during the isothermal melt crystallization process of the PLLA/PDLA stereocomplex. A very small low-frequency shift (about 1 ...
