Abstract
The present invention relates to chlorine resistant crosslinkable silane-containing polyolefin compositions and stabilizer masterbatch compositions, their preparation, and articles made therefrom. These crosslinkable silane-containing compositions contain a mixture of antioxidants, light absorbers and stabilizers that provide resistance to the levels of chlorine used in potable water and to light, thereby extending the useful life of said articles made therefrom, such as potable water pipes and valves, bottles, tanks, and the like.
