Abstract
The present invention relates to a polyolefin composition with increased resistance to degradation caused by ClO2-containing water and to a pipe made of such a polyolefin composition. The present invention further relates to the use of the polyolefin composition for the production of a pipe and to the use of a combination of particular types of antioxidants for increasing the resistance of the polyolefin composition against degradation caused by contact with ClO2-containing water.
