Abstract

L'invention concerne des résines polyester insaturé à faible viscosité. Elles sont essentiellement constituées de : a. un alkyde préparé par estérification, notamment de l'anhydride maléique en mélange avec l'anhydride phtalique et d'un ou plusieurs glycols, notamment le dipropylène-glycol et, b. un dimonomere à saturation éthylique copolymérisable avec a, notamment le styrène, le rapport poids moléculaire/doubles liaisons de l'alkyde étant compris entre 200 et 360 et la teneur en radicaux fonctionnels libres exprimée en mg de KOH par gramme d'alkyde a, étant comprise entre 80 et 100. Application à la fabrication de produits renforcés par des fibres de verre.
