Claim 0:
1. A method for producing a propylene copolymer, comprising extruding a molten propylene copolymer and a composition essentially comprising at least one peroxydicarbonate and at least one other organic peroxide, wherein extruding is performed by extruding the propylene copolymer, adding the composition to the propylene copolymer, and melt extruding the propylene copolymer in the presence of the composition,
wherein the propylene copolymer melt extruded in the presence of the composition presents a melt flow rate (MFR) higher than the MFR presented by the propylene copolymer before the extrusion, and
wherein the propylene copolymer melt extruded in the presence of the composition presents an elasticity ratio (ER) higher than the ER presented by the propylene copolymer before the extrusion.
