Polypropylene composition for extrusion coating

A propylene polymer composition having improved extrudability, comprising (a) a crystalline polypropylene having a melt flow rate at 230.degree. C. of at least 3, (b) low density polyethylene having a density of 0.915 to 0.920, a melt index of 3 to 15 and a G.sub.c value of at least 2.5.times.10.sup.5, and (c) a copolymer of vinyl toluene and alpha-methyl styrene, which has been hydrogenated to the point where at least 50% of its aromatic unsaturation has been reduced, and which has a drop softening point from about 100.degree. to 160.degree. C., component (b) being from 3 to 15 parts by weight per 100 parts of (a), component (c) being from 2 to 10 parts by weight per hundred parts of (a), and the total of (b) and (c) being 7 to 20 parts per hundred parts of (a).
