    • The present invention relates to a polyolefin composition comprising (i) a polyolefin (A), (ii) a benzil derivative (B) comprising the, preferably consisting of the, structural unit according to the following formula (I). wherein one or more of the carbon atoms in the phenyl rings to which residue R1, R2, R3, R4, R5, R6, R7, R8, R9 or R10 is attached may also be a heteroatom, such as N, in which case the respective residue R1, R2, R3, R4, R5, R6, R7, R8, R9 or R10 is not present; R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 independently are hydrogen, or a hydrocarbyl group which may contain heteroatoms; or at least two of said R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 together with the ring atoms of the ring system of formula (I) they are attached to, form a further aromatic or non-aromatic ring fused to the ring system of formula (I), and wherein the ring system of formula (I) with said at least one fused further ring may further bear one to eight substituents, R1' to R8', each of which are independently selected from said same groups as R1 to R10; and n = 2 to 9; with the proviso that (i) at least one of said R1, R2, R3, R4, R5, R6, R7, R8, R9 or R10, or if present, at least one of said R1' to R8', is a hydrocarbyl group which may contain one or more heteroatoms.
    • 本发明涉及一种聚烯烃组合物,其包含(i)聚烯烃(A),(ii)包含根据下式(I)的结构单元优选由其组成的苯偶酰衍生物(B)。 其中R1,R2,R3,R4,R5,R6,R7,R8,R9或R10所连接的苯环中的一个或多个碳原子也可以是杂原子,例如N,在这种情况下, 不存在残基R1,R2,R3,R4,R5,R6,R7,R8,R9或R10; R 1,R 2,R 3,R 4,R 5,R 6,R 7,R 8,R 9和R 10独立地为氢或可含有杂原子的烃基; 或者所述R 1,R 2,R 3,R 4,R 5,R 6,R 7,R 8,R 9和R 10中的至少两个与式(I)的环系统的环原子连接,形成另外的芳族或非 - 芳环与式(I)的环系稠合,并且其中具有所述至少一个稠合的另外的环的式(I)的环系可以进一步具有一至八个取代基,R 1'至R 8',其各自为 独立地选自与R1至R10相同的基团; n = 2〜9; 条件是(i)所述R 1,R 2,R 3,R 4,R 5,R 6,R 7,R 8,R 9或R 10中的至少一个,或如果存在,所述R 1'至R 8'中的至少一个为烃基 可以含有一个或多个杂原子的基团。
