A PROCESS FOR PREPARING POLYESTER RESINS FROM POLYETHYLENE TEREPHTHALATE AND ENERGY CURABLE COATING COMPOSITIONS |
摘要 |
The present invention is directed to polyester resins which are prepared by depolymerizing virgin, scrap, recycled or reclaimed polyethylene terephthalate (PET) via an alcoholysis reaction with one or more polyhydric alcohols to form a depolymerization product and esterifying the depolymerization product with one or more polybasic carboxylic acids and/or anhydrides and optionally polyhydric alcohol to form a polyester polyol. The polyester may then be acrylated with acrylic acid to form a polyester acrylate resin. The polyester resins are then used in energy curable coating compositions or inks and in particular, the polyester acrylate resin is suitably used as a reactive binder/oligomer. |
