Soft drinks poly (ethylene terephthalate)(PET) bottles were depolymerized by glycolysis with
different molar ratio of glycol, such as propylene glycol (PG), triethylene glycol (TEG) and
poly (ethylene glycol)(PEG 400), in the presence of a zinc acetate catalyst. These glycolyzed
products were characterized by hydroxyl value (HV) determinations. The obtained
glycolyzed products were reacted with isophorone diisocyanate (IPDI), dimethylol propionic
acid (DMPA), as potential ionic center for water dispersibility, and mixed with ethylene …
