THE PRESENT INVENTION REALTES TO CONTAINERS OR LININGS FORMED FROM THERMOPLASTIC POLYMERIC WHICH ARE SUITABLE FOR USE IN TRANSPORT AND STORAGE OF AQUEOUS OXIDISING AGENTS AND TO THE THERMOPLASTIC POLYMERIC MATERIALS THEMSELVES. THE THERMOPLASTIC POLYMERIC MATERIALS SUCH AS POLYETHYLENE, FORMING THE CONTAINER OR LININGS ARE STABILISED AGAINST EMBRITTLEMENT CAUSED BY INTERACTION WITH THE PERACID SOLUTION 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 STOPRED 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. |
