A propylene polymer composition comprising (percent by weight referring to the sum of A+B): A) 60%-90% of a crystalline propylene copolymer containing from 1.0% to 5.0% of ethylene derived units; B) 10%-40% of a copolymer of propylene with from 18% to 32% of ethylene derived units, said propylene polymer composition having a melt flow rate value according to ISO 1133 (230&#xb0; C., 2.16 kg) of from 1.0 to 2.0 g/10 min.

Continuous feed of auxiliaries for the polymerization reaction of ethylene, propene, and other higher homologous olefins in the preparation of homo- and copolymers, avoiding production of inhomogeneities, such as lumps or chunks which are present because the condition of the auxiliaries is not suitable for precise metering, becomes possible when auxiliaries in paste or solid form, in particular antistatic auxiliaries, are subjected, prior to feed, to a heat treatment in the presence of a solvent at a temperature of from 20 to 80&#xb0; C., and then recooled, and then fed to the polymerization reaction.
