An Easy Access to the Exocyclic Lactams Analogous of the Central Nervous System Active Tricyclic Nitroxapine, Mianserine and Chlothiapine Agents Using N-Acyliminium Chemistry
An Easy Access to the Exocyclic Lactams Analogous of the Central Nervous System Active Tricyclic Nitroxapine, Mianserine and Chlothiapine Agents Using N-Acyliminium Chemistry
The present invention relates to resin compositions adapted for weather, heat and light resistance, and which are also resistant to discolouration, comprising at least one polymeric substance and:
(A) a hindered amine stabiliser;
(B) a hindered-phenol-hindered amine stabiliser; and
(C) a UV absorber,
in amounts sufficient to confer resistance to discolouration on the composition.
