Abstract
A thermoplastic mixture is described that includes at least one impact-resistant polypropylene copolymer and at least one ethylene-1-octene copolymer. The weight ratio of impact-resistant polypropylene copolymer to ethylene-1-octene copolymer can be in the range of 35:65 to 65:35. The thermoplastic mixture has a high melting point and excellent flexibility. The mixture is suitable in particular for roof membranes and waterproofing membranes.
