Abstract

Polyolefin compositions comprising: A) a heterogeneous polyolefin composition itself comprising a fraction (A1) which is insoluble in xylene at room temperature and a fraction (A2) which is soluble in xylene at room temperature; and B) a branched propylene polymer. The said compositions are particularly processable when used in the process for the preparation of blown films. The films obtained by the said process are moreover characterized by excellent mechanical properties.
