Fig. 2: Kinetics of PLLA crystallization.

From: Ring-opening polymerization-induced crystallization-driven self-assembly of poly-L-lactide-block-polyethylene glycol block copolymers (ROPI-CDSA)

Fig. 2

a, b WAXS pattern for PLLA45-b-PEG45 (10% solids w/w 9) (a) and PLLA90-b-PEG45 (10% solids w/w 15) (b) over time and c, d FTIR spectra of the carbonyl shift for 9 (c) and 15 (d). Note for (a), from 24 h to 168 h, no significant difference is observed. For (b), from 3 h to 24 h, no significant difference is observed. Note that for (a), 5 min and 1 h, and 2b, 5 min show metastable crystalline intermediates. The data show a development in the crystallinity over time indicating that the self-assembly process measured in Fig. 1 is related to the crystallization of the PLLA core-forming block.
