Patent

CA 2207142

The present invention relates to a process for the hydrolysis of plastics which contain hydrolytically decomposable chemical bonds (groupings) in the polymer chain, which is characterized in that the plastics used are treated with water in the presence of a hydrolysate of the same or a similarly composed plastic, at temperatures from 20 to 240°C, optionally under pressure, until the plastic to be hydrolyzed is completely dissolved in the hydrolysis mixture.

Procédé pour l'hydrolyse de matières plastiques renfermant dans la chaîne polymérique des liaisons chimiques (groupes) décomposables par hydrolyse; l'invention est caractérisée par le fait que les plastiques utilisés sont traités avec l'eau en présence d'un hydrolysat du même plastique ou d'un mélange plastique analogue, à des températures de 20 à 240 degrés C, facultativement sous pression, jusqu'à ce que le plastique à hydrolyser soit complètement dissous dans le mélange d'hydrolyse.
