Abstract

Résines de polyester insaturé à faible viscosité. Résines de polyester insaturé à faible viscosité pour préparer des produits éventuellement renforcés par des fibres de verre. Elles sont constituées par un alkyle préparé par estérification d'anhydride maléique et/ou d'acide maléique et/ou d'acide fumarique en association avec de l'acide isophtalique, et avec un ou plusieurs glycols contenant de plus 25 à 40 % en poids par rapport à la totalité de la résine d'un monomère à insaturation éthylénique copolymérisable avec l'alkyde choisi parmi essentiellement le styrène et le vinyltoluène, l'alkyde ayant un rapport poids moléculaire/doubles liaisons de 300 à 390 et une teneur en radicaux fonctionnels libres de 50 à 85 mg de KOH/g d'alkyde.
