摘要：

The recycling of post-consumer poly(ethylene terephtalate) (PET) is a worldwide concern due to its environmental impact and the large and increasing volume of these materials produced by society. We use post-consumer PET in alkyd resin synthesis for coatings, replacing a fraction of phthalic anhydride (PA) and ethylene glycol (EG) of conventional synthesis for post-consumer PET. The chemical and physical properties of resins can be modified depending on the reagents used, the ratio between them and the method of synthesis chosen. In this investigation, we present the alkyd resin synthesis using many vegetable oils and fatty acids. The alkyd resins obtained were characterized by conventional techniques such as acid value (AV), viscosity, drying time and infrared spectroscopy (FT IR). (C) 2006 Elsevier B.V All rights reserved.
