    摘要： The invention relates to a polymer composition comprising a polyolefin (A) and an antioxidant. The antioxidant can be selected from a phenol which bears two substituents both containing a sulfur atom and optionally further substituent(s). The polymer composition can comprise vinyl groups/1000 carbon atoms in an amount of 0.15/1000 carbon atoms or more. The polymer composition can have improved water tree resistance properties.
