| Abstract: | Biomaterial
based polyhydric compounds were synthesized and utilized for the
depolymerization of PET. Three different oligomers were synthesized by using 5,
15 and 25% PET. Depolymerized oligomers were esterified with dehydrated castor
oil (DCO) fatty acids to give polyester polyols. Polyurethane adhesives were
synthesized using these polyols for joining rubber-rubber assembly. Bond
strength was measured by 180° peel
test. Mode of failure was studied by scanning electron microscopy (SEM)
analysis. Depolymerised PET oligomers, polyols and polyurethane were
characterized by FTIR spectroscopy. Also, polyurethane adhesives were evaluated
for their performance and chemical resistance. |
