Abstract:
A polyolefin composition with improved bondability consisting essentially ofA) at least one polyolefin; and B) at least 0.001% by weight, based on the polyolefin of at least one ionic polymerization initiator capable of initiating the polymerization of monomers corresponding to formula I â€ƒin which R1 represents â€”CN or COOR3, R2 represents â€”CN or COOR3, and R3 represents hydrogen, a linear or branched, saturated or unsaturated, similar or different alkyl group or cycloalkyl group containing 1 to 22 carbon atoms or a phenyl group; wherein components A) and B) have been mixed together at a temperature above the glass transition temperature of the polyolefin; and wherein the at least one ionic polymerization initiator is selected from the group consisting of imidazolines, imidazolinones and polyazapolycycles.
