PROCESS FOR THE STABILIZATION IN STORAGE OF POLY- -CAPROLACTONES.

Les poly-epsilon-caprolactones produites par polymérisation continue en masse fondue d'epsilon-caprolactone à l'intervention d'alkoxydes d'aluminium sont stabilisées au stockage par incorporation d'une quantité efficace de dérivé de silicium tel que, par exemple, un oxyde de silicium, un silicate inorganique ou un alkoxyde de silicium, la préférence étant donnée aux alkoxydes de silicium. Ce procédé a pour effet de limiter fortement la réduction progressive au cours du temps de la viscosité inhérente des poly-epsilon-caprolactones. Suivant un mode de réalisation préféré, on fait précéder l'incorporation du dérivé de silicium par l'incorporation d'une quantité efficace d'eau, ce qui améliore encore la stabilité au stockage des poly-epsilon-caprolactones produites à l'intervention d'alkoxydes d'aluminium. The poly-epsilon-caprolactones produced by continuous melt polymerization of epsilon-caprolactone with the intervention of aluminum alkoxides are stabilized on storage by incorporation of an effective amount of silicon derivative such as, for example, a silicon oxide, an inorganic silicate or a silicon alkoxide, preference being given to silicon alkoxides. This process has the effect of greatly limiting the gradual reduction over time of the inherent viscosity of poly-epsilon-caprolactones. According to a preferred embodiment, the incorporation of the silicon derivative is preceded by the incorporation of an effective amount of water, which further improves the storage stability of the poly-epsilon-caprolactones produced by the intervention of 'aluminum alkoxides.

Process for the storage stabilization of poly-ε-caprolactones

Poly-ε-caprolactones produced by continuous melt polymerization of ε-caprolactone with the use of aluminium alkoxides are stabilized for storage by incorporation of an effective quantity of silicon derivative such as, for example, a silicon oxide, an inorganic silicate or a silicon alkoxide, preference being given to silicon alkoxides.
