摘要
1. A thermoplastic molding material based on a mixture of (A) from 20 to 50 parts by weight of asphalt which has a penetration at 25 degrees C of from 3 to 100 according to DIN 1995, (B) from 40 to 70 parts by weight of an ethylene polymer, (C) from 0 to 5 parts by weight of carbon black, (D) from 0 to 5 parts by weight of glycerol monostearate and (E) from 0 to 30 parts by weight of a conventional filler, wherein the ethylene polymer (B) is a copolymer of from 97 to 80% by weight of ethylene and from 3 to 20% by weight of a C4 -C10-alpha -olefin and has a density of from 0.89 to 0.93 g/cm**3 and a crystallite melting point of from 115 to 125 degrees C, the molding material containing no ethylene/vinyl ester or ethylene/acrylate copolymer.
