Abstract

Propylene polymers contain A) a semicrystalline propylene homopolymer having a melting point of 125 to 165.degree. C. and a glass transition temperature which is greater than -10.degree. C. and B) a semicrystalline propylene homopolymer having a melting point below 130.degree. C. and a glass transition temperature which is less than or equal to -10.degree. C. or a non-crystallizing propylene homopolymer having a glass transition temperature which is less than or equal to -10.degree. C.
