ABSTRACT: Polyethylene ( PE) has been modified by a small [2]
amount of mixing ethyleneacrylic acid ( EAA) copolymer. The
w ater treeing in PE modified was also studied. The paper analy [3]
, ,
ses the reason forming water treeing in PE and mechanism sup , ,
pressing water treeing. The condition forming water treeing is
,
w ater drop existing in the structure defect in PE. And the [ ]
method suppressing the water treeing is just reducing water
drop. We found an optimum EAA content suppressing water
,
t reeing. PE sample with 1.0% w t EAA can be studied furt her
in cable insulation.
