Compositions of high molecular weight low pressure polyethylene having a very high molecular weight, a melt index of from 0.1 to 20g/10 min. measured with a 21.6 kg weight and ethylene- (meth)acrylate copolymers 1-25% weight of the polyethylene can be prepared and further treated at required high temperatures without giving off corrosive acid degradation products. They are particularly suitable for the production of pipes and cable materials, and especially for crosslinked pipes. Compositions containing additives, such as organic additives and fillers, are advantageously prepared using the ethylene-(meth)acrylate copolymer as carrier material for the additives. |
