1H NMR Spectroscopy in the Analysis and Characterization of Poly(lactide)

Autor: Eric Stanley Hall, Khalid A. M. Thakur, Jeffrey John Kolstad, Robert T. Kean, Eric J. Munson

Publikováno v: International Journal of Polymer Analysis and Characterization. 4:379-391

High resolution 500 MHz 1H NMR spectroscopy is a powerful tool for the analysis and characterization of poly(lactide) (PLA). It accurately provides information about the distribution of a few stereosequences in the polymer whose resonances are well-r

Reversible Kinetics and Thermodynamics of the Homopolymerization of l-Lactide with 2-Ethylhexanoic Acid Tin(II) Salt

Autor: David R. Witzke, Ramani Narayan, Jeffrey John Kolstad

Publikováno v: Macromolecules. 30:7075-7085

The reversible kinetics of l-lactide bulk polymerization with tin(II) ethylhexanoate was determined over a wide range of temperatures, 130−220 °C, and monomer to initiator molar ratios, 1000−80 000. Both polymerization and depolymerization are a

High-Resolution 13C and 1H Solution NMR Study of Poly(lactide)

Autor: Eric J. Munson, Timothy A. Lindgren, J. Ilja Siepmann, Robert T. Kean, Matthew A. Doscotch, Khalid A. M. Thakur, Jeffrey John Kolstad, Eric Stanley Hall

Publikováno v: Macromolecules. 30:2422-2428

High-resolution 500 MHz solution-state 1H and 13C NMR spectra of various poly(lactides) indicate at least hexad stereosequence sensitivity. The poly(lactides) were prepared in vials by melt polymerization of various combinations of l-lactide, d-lacti

Crystallization kinetics of poly(L-lactide-co-meso-lactide)

Autor: Jeffrey John Kolstad

Publikováno v: Journal of Applied Polymer Science. 62:1079-1091

The crystallization kinetics of poly(L-lactide-co-meso-lactide) were determined over a range of 0% to 9% mesolactide. The kinetics were fit to the nonlinear Avrami equation and then to the Hoffman–Lauritzen equation modified for optical copolymers.
