title: Polymerization of cyclic esters initiated by carnitine and tin (II) octoate.
abstract: Low-molecular weight poly(epsilon-caprolactone), polylactides and copolymers of epsilon-caprolactone and lactides were obtained by the polymerization of cyclic esters in the presence of a carnitine/SnOct(2) system. Their structures were proven by means of MALDI-TOF, IR and NMR studies. Effects of temperature, reaction time and carnitine dosage on the polymerization process were examined.
