Effect of polymerization degree on building-up helical structure of OligO(L-lactic acid)
We synthesized oligo(L-lactic acid) with almost mono dispersion by using GPC fractionation technique, and could confirm from the circular-dichroic spectra that the number of repeating units of 8 to 10 was enough to build up the helical structure.
