| titleOfInvention | Process for Preparing Modified Polypropylene Compositions |
| abstract | The invention relates to a process for producing a modified polypropylene composition comprising a step of adding at least one organic peroxide, a poly(n)functional acrylate, with n≧2, as co-agent, in a peroxide:co-agent mass ratio of from 1:0.4 to 1:5, and an acid scavenging compound, to a heterophasic propylene copolymer comprising from 50 to 99% by mass of a matrix phase, based on the total mass of the heterophasic propylene copolymer, comprising a propylene homopolymer and/or a propylene copolymer comprising at least 70% by mass of propylene and up to 30% by mass ethylene, based on the total mass of the matrix phase polymer, and/or at least one C 4 to C 10 alpha-olefin, and from 1 to 50% by mass dispersed phase, based on the total mass of the heterophasic propylene copolymer, comprising an ethylene-alpha-olefin elastomer consisting of more than 20% by mass ethylene and up to 80% by mass of at least one C 3 to C 10 alpha-olefin, based on the total mass of the dispersed phase elastomer. The invention also relates to a modified polypropylene composition characterized by an elasticity index n n n n n p n = n n n ER n λ n n y n n n n n n of at least 1, wherein: ER λ is the melt elasticity at G′=G″ at λ; G′ is the storage modulus; G″ is the loss modulus; λ is the value of G″ at which G′ is determined; y=0.5λ+200; and/or by an Izod impact strength at −20° C. measured according to ISO 180 4A of higher than 50 kJ/m 2 . The invention further relates to a moulded article comprising the modified polypropylene composition. |
