Development of Primer as a Value Added Product from Waste PET
Abstract: Polyethylene terephthalate was depolymerized by two different chemical recycling techniques i.e. glycolysis and aminolysis. Glycolysis is carried out with Zinc hydroxide and with conventional catalyst i.e. Zinc acetate for the comparable yield of the monomer. Glycolysis is carried out with ethylene glycol whereas aminolysis is done with ethanolamine. Products obtained from both the techniques namely Bis(2-hydroxyethyl) terephthalate (BHET) and Bis(2-hydroxyethyl) terephthalamide (BHETA) have different chemical structure but have hydroxyl functionality …

Application of Poly (o-anisidine) Nanocomposite and PET Recycled Polyester Amide in Anticorrosive Coatings
Abstract: AbstractPolyethylene terephthtalate (PET) was depolymerized through aminolysis technique using ethanolamine into Bis (2-hydroxyethylene) terepthalamide (BHETA). BHETA is having hydroxyl functionality present in it so it is used as monomer and treated with sebacic acid using sulphuric acid as a catalyst. The synthesized resin having ester linkage present in it along with that in BHETA, amide linkage is also present hence it can be called as polyesteramide resin. This synthesized carboxyl …
