Abstract (en)
[origin: WO8101706A1] Novel compounds, compositions and methods for stabilization of ultraviolet light sensitive polymers against photodegradation. The novel secondary and tertiary amines of this invention can be represented by the following structural formula: (FORMULA) with R and R' being independently selected from the group consisting of alkyl, hydroxy substituted alkyl, aryl, amino or hydroxy substituted aryl, aralkyl and amino or hydroxy substituted aralkyl; R<u1>u and R<u2>u being independently selected from hydrogen, alkyl, aralkyl; R<u3>u and R<u4>u being independently selected from alkyl of 1 to 4 carbon atoms and capable of collectively forming a cycloalkyl substituent; A and A' being independently selected from the group consisting of alkylene of 1 to 12 carbon atoms; and m is 0-4; n is 1-3. The above compounds are especially suitable in the stabilization of polyolefins (i.e. polypropylene) against the degradative forces of ultraviolet light.

Nouveaux composes, compositions et procedes de stabilisation de polymeres sensibles a la lumiere ultraviolette contre la photodegradation. Les nouvelles amines secondaires et tertiaires de cette invention peuvent etre representees par la formule suivante: (FORMULE) R et R' etant choisis independamment parmi le groupe comprenant un alkyle, un alkyle a substitution hydroxy, un aryle un aryle a substitution hydroxy ou amino, un aralkyle et un aralkyle a substitution hydroxy ou amino; R1 et R2 etant choisis independamment parmi l'hydrogene, un alkyle, l'aralkyle, R3 et R4 etant choisis independamment un alkyle de 1 a 4 atomes de carbone et capables de former collectivement un substituant de cyclo alkyle; A et A' etant choisis independamment parmi le groupe consistant en alkylene de 1 a 12 atomes de carbone; et m a une valeur de 0 a 4, et n de valeur 1 a 3. Les composes ci-dessus sont specialement appropries pour la stabilisation de polyolefines (polypropylene) contre les forces de degradation de la lumiere ultraviolette.
