METHOD FOR PRODUCING A TEMPOL-CONTAINING URETHANE RESIN COMPOSITION HAVING AN IMPROVED STORAGE STABILITY

The present invention relates to a method for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the d...

Beschreibung
Zusammenfassung:	The present invention relates to a method for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the degradation of TEMPOL in mixtures with branched urethane resins. La présente invention concerne un procédé de préparation d'une composition de résine uréthane (méth)acrylate. Le procédé améliore la stabilité au stockage et réduit la dérive de réactivité de la composition par rapport à des compositions qui ont été préparées par d'autres moyens à partir des mêmes produits de départ. Ce procédé permet en particulier de réduire la décomposition de TEMPOL dans des mélanges avec des résines uréthanes ramifiées.
