A process for the solid state upgrading of a polyester resin by polyaddition reaction in which the resin is upgraded in the presence of an upgrading additive which is a compound different from a dianhydride of an aromatic tetracarboxylic acid, containing two groups capable of addition reactions with the terminal groups of the polyester, selected for example in the group of the dianhydrides of aliphatic and cycloaliphatic tetracarboxylic acids.
On décrit un procédé de valorisation à l'état solide d'une résine polyester par une réaction de polyaddition, dans laquelle la résine est valorisée en présence d'un additif de valorisation, ledit additif étant un composé autre qu'un dianhydride d'un acide tétracarboxylique aromatique, contenant deux groupes susceptibles d'engendrer des réactions d'addition avec les groupes terminaux du polyester, et choisis par exemple dans le groupe des dianhydrides d'acides tétracarboxyliques aliphatiques et cycloaliphatiques.
