The properties of water absorbing and water treeing in polyethylene and polyethylene modified samples were studied.
对聚乙烯及改性聚乙烯的吸水特性和水树形成规律进行了研究。
The result shows that the formation of water treeing in polyethylene modified samples were inhibited, although they have a high water absorbing capacity.
实验结果发现，尽管改性聚乙烯有较大的吸水率，但却可以抑制水树的形成。
Different mechanisms to inhibit water treeing were found for ethylene-acrylic acid(EAA)copolymer and sorbital.
乙烯-丙烯酸共聚物（EAA）和三梨糖醇在抑制聚乙烯的水树形成机理上有所不同。
