<p>A polyolefin-based thermoplastic formulation giving products with soft-touch and functionalized to be welded and painted comprises, by weight of the total weight of the polymers, 10-80% of polypropylene, 0-85% by weight of EP(D)M rubber, 0-40% of polybutadiene, and 0,5-60% of at least one unsaturated compound selected from: ethylene-vinyl acetate copolymers and terpolymers, NBR, ethylene-acrylic ester copolymers and terpolymers, and polybutadiene-based polyurethanes or their precursors, or mixtures thereof; with the proviso that the total amount of polybutadiene and unsaturated compounds is equal or less than 60% by weight. The formulation is prepared via visbreaking of the above listed compounds with radical-generating agents.</p> |
