It is described a thermoplastic composition comprising. (A) 10 to 99% by weight of a propylene polymer optionally containing from 0.1 to 5% by moles of units deriving from an olefin of formula CH2=CHR, R being hydrogen, a C2-C20-alkyl or a C6-C12-aryl group, having the following characteristics: 50<isotactic triads (mm)<85; melting point (Tm) from 60° C. to 120° C., and (B) 1 to 90% by weight of a propylene polymer having an essentially isotactic structure, optionally containing from 0.1 to 5% by moles of units deriving from an olefin of formula CH2=CHR, R being hydrogen, a C2-C20-alkyl or a C6-C12-aryl group, which has a melting point (Tm) higher than 153° C. It is also described a process for the preparation of said thermoplastic composition.
