    Abstract: PROBLEM TO BE SOLVED: To provide an improved propylene polymer which has good impact strength, flowability, and processability, a high stiffness, and a very low white fracture disposition. SOLUTION: This propylene polymer contains 50-95 pts.wt. propylene homopolymer having a melt flow index (measured according to ISO specification 1133 at 230 deg.C under a load of 2.16kg) of 0.1-100g/10min and an isotactic index of at least 98%, 5-50 pts.wt. ethylene copolymer (B) contg. 4-40wt.% polymerized 4-20C 1-alkene and having a density of 0.865-0.920g/cm , and 0-1.5 pts.wt. nucleating agent (C), the sum of ingredients A and B being 100 pts.wt.
