Abstract

Selon l'invention on fait réagir la colophane avec un polyalcool primaire en quantité au moins équivalente, on incorpore un acide arylsulfonique en quantité catalytique au début ou dans le cours de la réaction et on termine l'estérification. On obtient ainsi des esters présentant des colorations pâles, des points de ramollissement satisfaisants, et un indice d'acide inférieur à 20 environ.According to the invention, the rosin is reacted with a primary polyalcohol in at least an equivalent amount, an arylsulfonic acid is incorporated in a catalytic amount at the start or during the reaction and the esterification is terminated. Esters are thus obtained which exhibit pale colorations, satisfactory softening points, and an acid number of less than approximately 20.
