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. %K Carnitine %K Biomaterials %K Polycaprolactone %K Polylactide %K Ring-opening polymerization %U http://www.mdpi.com/1420-3049/14/2/621
