| abstract |
The invention relates to a stabilizing mixture containing: A) a certain sterically hindered amine which is, for example, at least one compound of formula (I): (CF DRAWING IN BOPI) where the radicals R1 are each independently hydrogen, a C1 -C8 alkyl group, -O **., -CH2 CN, C3 -C6 alkenyl, C7 -C9 phenylalkyl optionally substituted on the phenyl radical by one or more C1 -C4 alkyl groups, or an acyl group in C1 -C8; B) an oxide, hydroxide or organic salt of magnesium or zinc, or a hydrotalcite; and C) a UV light absorber and / or a pigment. This stabilizing mixture is useful for stabilizing a polyolefin against degradation caused by light. Field of application: Stabilizers for plastics. |
