Abstract:
The invention relates to a polypropylene composition which combines low sealing initiation temperature (SIT) and high melting point (Tm), thus having a broad sealing window.

Claim (Index 7):
A process for producing the polypropylene composition according to  claim 1  by a sequential polymerisation process comprising at least two reactors connected in series, said process comprising the steps:\n a) polymerising in a first reactor being a slurry reactor, preferably a loop reactor (R-1), propylene and one comonomer selected from C 4 -C 10  alpha-olefin obtaining a propylene polymer fraction (PPF1), being a propylene copolymer as defined in  claim 1 \n b) transferring the propylene polymer fraction (PPF1) and unreacted comonomers of the reactor (R-1) into a second reactor (R-2) being a first gas-phase reactor-1 (GPR-1), \n c) in the gas-phase reactor-1 (GPR-1) propylene, ethylene and one comonomer selected from C 4 -C 10  alpha-olefin are polymerised in the presence of the propylene polymer fraction (PPF1), obtaining a propylene polymer fraction (PPF2), being a propylene terpolymer as defined in  claim 1 , said propylene polymer fraction (PPF2) and the propylene polymer fraction (PPF1) forming the polypropylene composition according to  claim 1 , and \n d) recovering the polypropylene composition according to  claim 1 .
