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.
