Patent

CA 2282329

Compounds belonging to the group of enamines consisting of derivatives of .beta.-keto-esters, or .beta.-keto-amides or 1,3-diketones with primary or secondary aliphatic or aromatic amines carrying at least one sterically hindered amine group having general formula (I) in the molecule. The compounds having general formula (I) can be used as antioxidants for organic polymers.

Composés appartenant au groupe des énamines constituées par des dérivés de .beta.-kéto-esters ou de .beta.-kéto-amides ou de 1,3-dicétones avec des amines primaires ou secondaires aliphatiques ou aromatiques portant au moins un groupe amine à empêchement stérique représenté par la formule (I) dans la molécule. On peut utiliser ces composés en tant qu'antioxydants pour des polymères organiques.
