This paper presents an outline of developed methods for chemical recycling of postconsumer poly(ethylene terephthalate) (PET) waste bottles. Oligoesters (obtained by chemical recycled PET) with 2,2-bis (hydroxyl methyl) propionic acid, as hydrophobic monomer, and isophorone diisocyanate as cross-linker, in the presence of di-n-dibutyl tin(IV)dilaurate catalyst, were used for polyurethane dispersions. Molecular masses of obtained products were analyzed by gel permeation chromatography. Infra-red spectroscopy was used for molecular structures analysis. Thermal properties were evaluated by using differential scanning calorimetry and thermogravimetric analysis.References
