The present invention provides a process for the preparation of low styrene content resins prepared by first reacting an unsaturated carboxylic acid, its corresponding anhydride or mixtures thereof with a monohydric alcohol, DCPD and water and reacting the product of the first step with a polyol and optionally an oil containing unsaturation, its corresponding fatty acid or mixtures thereof.
La présente invention concerne un procédé d'élaboration de résines pauvres en styrènes pour lequel on commence par faire réagir un acide carboxylique insaturé, son anhydride correspondant ou certains de leurs mélanges avec un alcool monohydrique, du dicyclopentadiène (DCPD) et de l'eau, à la suite de quoi on fait réagir le produit de la première opération avec un polyol et éventuellement une insaturation grasse, l'acide gras correspondant ou certains de leurs mélanges.
