Polyesters having both α,β-unsaturated groups and moieties containing activated methylene or methine groups, such as those of beta- ketoacetate and malonate, are curable in the presence of a base catalysts to form crosslinked networks. Formulations based on such polyesters are suitable for use in coatings and adhesive applications, and have the characteristics of curing at temperatures less than 230 ° C without the use of isocyanates. |
