An ultraviolet radiation absorbing composition can be used as a light stabilizer for a shaped artificial polymer article, wherein the polymer is a synthetic polymer and/or a natural elastomer and wherein the ultraviolet radiation absorbing composition includes the compound of formula (I) wherein n and m are independently 0 to 20, and at least one of m and n being ≥1; and X1, X2, X3, X4 and X5 are the same or different and are independently selected from H, C(O)R1 with R1 being C-C-alkyl, or a group of the general formula (II) wherein R2 is H or halogen.

Use of an ultraviolet radiation absorbing composition as a light stabilizer for a shaped artificial polymer article

An additive mixture containing (A) at least one compound of the formula (I) wherein Rand Rindependently of one another are hydrogen, C-Calkyl, &#x2014;O&#x2014;, &#x2014;OH, &#x2014;CH2CN, C-Calkoxy, C-Calkoxy substituted by &#x2014;OH; C-Ccycloalkoxy, C-Calkenyl, C-Calkenyloxy, C-Cphenylalkyl unsubstituted or substituted on the phenyl by 1, 2 or 3 C-Calkyl; or C-Cacyl; and Rand Rindependently of one another are C-Calkyl or a group of the formula (Ia) wherein Rhas one of the meanings of Rand R, and (B) at least one anti-scratch additive. 

Additive mixture

The present invention relates to the use of NOR-HALS compounds in flame retardant polymer compositions. These compositions are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamines or polyesters and duro-plastic polymers, such as polyepoxides.
