Unsaturated Polyester Resins Based on Recycled PET: Preparation and Curing Behavior

摘要

The oligomers obtained from the glycolysis of Poly(ethylene terephthalate)(PET) waste were reacted with maleic anhydride to form a series of unsaturated polyester resins. The obtained resin was used to study teh curing reaction with styrene by differential scanning calorimetry. The heats of reaction for styrene and polyester inyl groups were measured by extrapolating the experimental results. Various kinetic parameters have been obtained using Kissinger expressions.
