This abstract first appeared for US patent application 18722651 titled 'HIGH IMPACT POLYPROPYLENE COMPOSITION

Original Abstract Submitted

A polypropylene composition includes at least 85 wt % a heterophasic propylene copolymer (A), 1.0 to 7.0 wt % a low density polyethylene (B), and 0.001 to 1.5 wt % an α-nucleating agent (C), wherein the heterophasic propylene copolymer (A) includes 75 to 90 wt % (a) a propylene homopolymer matrix and 10 to 25 wt % (b) an and wherein the ethylene-propylene copolymer comprises 43 to 57 wt % of units derived from ethylene and wherein the low density polyethylene (B) has a melt flow rate (MFR) using 2.16 kg at 230° C. and wherein the low density polyethylene (B) has a density of 915 to 932 kg/m, wherein the polypropylene composition has a total melt flow rate (MFR) of 30 to 150 dg/min, wherein the total melt flow rate is determined using ISO1133:2011 using 2.16 kg at 230° C., wherein the polypropylene composition satisfies the following inequation: 0.9<MFR/MFR<150.
