ENVIRONMENTAL STRESS CRACKING OF POLYETHYLENE

MODIFICATION OF THE GRIFFITH THEORY FOR THE PRESENCE OF LIQUIDS HAS BEEN SHOWN TO EXPLAIN SOME FACETS OF THE ENVIRONMENTAL STRESS CRACKING OF POLYETHYLENE. IN THE ABSENCE OF INTERCRYSTALLINE LINKS AND TIE MOLECULES, ONE IMPORTANT FACTOR IS THE TENSION GENERATED BETWEEN THE SPHERULITE BOUNDARY AND THE LIQUID ENVIRONMENT. JUDICIOUS INCORPORATION OF SILANES INTO POLYETHYLENE APPEAR TO REDUCE THE TENDENCY TO STRESS CRACKING BY MODIFYING THE INTERFACIAL TENSIONS BETWEEN THE ENVIRONMENT AND THE POLYMER. /AUTHOR/
