  • A novel approach for qualitative determination of residual tin based catalyst in poly(lactic acid) by X-Ray photoelectron spectroscopy = Nov način kvalitativne določitve vsebnosti katalizatorja kositra v polilaktični kislini z rentgensko fotoelektronsko spektroskopijo

    This work is focused on description of qualitative determination of residual tin based catalysts in poly(lactic acid) by using X-ray photoelectron spectroscopy and fluorimetry as standard technique. ... 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.
