摘要:
The disclosure relates to 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 organic peroxide. 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.
