wherein the composition having a total copolymerized comonomer content from 4% to 15% by mole, referred to the sum of A) and B), and a content of fraction soluble in xylene at 0 C. of 75% by weight or less, determined on the total weight of A) and B).

The invention provides adhesives comprising at least one polymer component which contains at least 65 weight percent propylene, at least one nucleator and at least one functionalized wax. The inventive adhesives have increased heat resistance and decreased set-time, making them particularly well suited for assembly and packaging applications.
