A polyolefinic composition comprising as component a) one or more compounds of formula I to IIIin whicheach R1 independently is selected from linear or branched C1-30alkyl, C5-12cycloalkyl, C2-24alkenyl, C2-18alkoxyalkyl, C2-19methoxyalkanoyl, C7-30alkaryl, C7-30aralkyl, C4-24heteroaryl (where any one of the above substituents of R1 are unsubstituted or are substituted by 1 to 3 groups selected from C1-12alkyl, -OR4, -NR4R5, -COR4 and -COOR4); and C6-30aryl, unsubstituted or substituted by 1 to 5 groups R3 selected from C1-12alkyl, C1-8alkoxy, C5-6cycloalkyl, phenyl or phenoxy, -OR4, -NR4R5, -COR4 and -COOR4,R4 and R5 independently are selected from hydrogen, C1-30alkyl (linear or branched), C5-12cycloalkyl, C6-24aryl, C7-30alkaryl or C7-30aralkyl;A is a direct bond, a group -(P-R1)p- or an n-valent aliphatic or aromatic residue, (preferably C1-30alkylene (linear or branched), C5-12cycloalkylene, C7-30alkarylene, C7-30aralkylene, C6-24arylene, a N-, O-, S-, or P- containing C6-24heteroarylene, C2-30alkylidene or C2-30alkylene interrupted by N, O or S); provided that when n is 2 then A is -CH2- or C5-30alkylene;m is 3 to 12; preferably 4-6n is 2 to 5; andp is 1 to 12; preferably 1-5the compounds of formulae I to III, andcomponent b) a polyolefin which has been produced in the presence of a Ziegler or metallocene type catalyst which has not been removed.
