Abstract:Chemical recycling of Polyethylene terephthalate (PET) waste has gained importance in last few decades due to its dramatic consumption through its variety of applications. This study employed conventional heating-mediated glycolysis of PET waste with excess ethylene glycol, catalyzed by zinc acetate, to achieve the monomeric product bis(2-hydroxyethyl terephthalate) (BHET). Further ,three different hybrid unsaturated polyester urethane resins were synthesized using recycled product BHET, urethane diol which wa… Show more
