摘要： Containers or linings formed from thermoplastic polymeric materials are provided which are suitable for use in transport and storage of aqueous oxidizing agents and the thermoplastic polymeric materials themselves. The thermoplastic polymeric materials such as polyethylene, forming the container or linings are stabilized against embrittlement caused by interaction with peracid solutions they contact by the incorporation of a thioether and preferably a hindered phenol anti-oxidant. The thioether particularly comprises additionally a hindered phenol and is, for example, a thiobisphenol. The stored peracid solutions exhibited improved storage stability. The containers or linings are particularly suitable for storing or transporting aqueous peracid solutions in locations enjoying relatively high ambient temperatures.
