Resumen:
Recycled and pristine low-density polyethylene samples were crosslinked by 60Co gamma rays in the presence of two commercial sensitizers:trimethylolpropanetriacrylate (TMPTA) and trimethylolpropanetrimethacrylate (TMPTMA), and another laboratory-synthesized sensitizer, hexakisalylaminocyclotriphosphazatrine (HAAP). The gel per cent and radiochemical yields for crosslinking and degradation were determined for both recycled and pristine polyethylene. TMPTA was found to be the most efficient sensitizer. The gel dose did not change significantly with different sensitizers. © 2001 Elsevier Science Ltd.
