Three types of poly(lactic acid) were prepared by direct melt polycondensation of lactic acid by using methanesulfonic acid (w = 0.5 %) or various amount of stannous 2-ethylhexanoate (w = (0.5 and 2) %). The results from both methods show that the amount of observed tin in the samples correlates with the concentration ofthe stannous 2-ethylhexanoate used for polycondensation. X-ray photoelectron spectroscopy was proven to be suitable for detection of tin residuals in polymer matrix"},{"@xml:lang":"sl","#text":"Delo je osredinjeno na opis kvalitativne določitve katalizatorjev na osnovi kositra v polilaktični kislini z uporabo rentgenske fotoelektronske spektroskopije in fluorimetrije.
