Abstrakt: The effects of various waterblocking gels are investigated in relation to swelling behavior of polyolefins. Gel absorption is studied in polyethylene and polypropylene/ethylene copolymers as a function of temperature for a density range of 0.868 g/cc to 0.948 g/cc for polyethylene and 0.88 to 0.91 g/cc for propylene/ethylene copolymers. The effect of swelling on antioxidant extraction is also studied as a function of antioxidant molecular weight and degree of swelling. Both factors show a strong influence on the amount of antioxidant extracted. A direct correlation is found between antioxidant extraction by gels and reduction in thermo-oxidative stability.
