ABSTRACT:
Process for cross-linking polypropylene, propylene copolymers, polyethylene, ethylene/propylene and ethylene/propylene/diene elastomeric copolymers and mixtures of said elastomers with above said thermoplastic polyolefins, which consists in modifying the polymer in the molten state, by the addition of 0.01%-10% by weight of carboxylic acid, possibly in the presence of a generator of radicals and by the subsequent salification with metal ions of the thus grafted carboxylic groups. The polymer products thus obtained display considerably improved characteristics under heating. In particular, there are obtained improved processability and elastic recovery characteristics for thermoplastic rubbers.
