Beschreibung
Zusammenfassung:	Disclosed are thermoplastic elastomeric compositions include:A) from 10 to 80% by weight of one or more crystalline polymer of propylene containing from 0.05 to 15% in moles of ethylenic unsaturation, or a mixture of the above polymer with a saturated thermoplastic olefin polymer in quantities lower than or equal to 80% by weight;B) from 20 to 90% by weight of an unsaturated elastomeric olefin polymer;the compositions having been dynamically cross-linked with a cross-linking agent which includes a free radical generator.
