Abstract: A polymer blend obtained by melt blending a mixture made from or containing:



(A) 60% to 98.8% by weight of a polyolefin;
(B) 0.1% to 30% by weight of a compatibilizer;
(C) 0.05% to 20% by weight of an amino resin; and
(D) 0% to 5% by weight of an additive,
wherein the amounts of (A), (B), (C), and (D) are based on the total weight of (A)+(B)+(C)+(D), the total weight being 100%.

Abstract: Heterophasic copolymers of propylene having a MFR2 (230° C./2.16 Kg) of from 3.0 to 12.0 g/10 min made from or containing:
(a) from 55 to 75 wt. % of a component (A) being a copolymer of propylene with ethylene or a C4-C10 alpha-olefin, made from or containing from 0.5 to 2.0 wt. % of ethylene and/or C4-C10 alpha-olefin units and having a MFR2 (230° C./2.16 K g) ranging from 60 to 140 g/10 min; and

(b) from 25 to 45 wt. % of a component (B) being a propylene-ethylene copolymer made from or containing from 25 to 45 wt. % of ethylene units and having a value of the intrinsic viscosity of the fraction soluble in xylene at room temperature (XS-IV) ranging from 5 to 9 dl/g.
