Preparation and properties of acacia sawdust/UPR composite based on recycled PET

Polyethylene therephthalate (PET) waste bottles had been depolymerized by glycolysis and reduced to its monomer and dimer. The glycolysed product was used to produce unsaturated polyester resin (UPR). DSC and FTIR analysis were conducted on the resin and the glycolysed product. The resin was then...
