Polyethylene ( PE ) have been modified by various contents of ethylene acrylic acid copolymer ( EAA ). 通过添加不同含量的乙烯-丙烯酸共聚物(EAA)改善了聚乙烯(PE)的电气性能。
The cross linked polyethylene ( XLPE ) have been modified by a small amount of ethylene acrylic acid copolymer ( EAA ). The Electro acoustic pulse method is used to observe the space charge distributions in samples. 以不同含量的EAA(乙烯丙烯酸(EAA)共聚物)改性XLPE(交联聚乙烯),用电声脉冲法测量了样品中的空间电荷分布。
The water absorbing properties of PE, XLPE and samples with ethylene acrylic acid ( EAA ) are studied by the comparison analysis. The space charge distributions of samples after water absorbing are determined. 通过对比研究了纯PE、XLPE以及含乙烯&丙烯酸共聚物(EAA)试样的吸水性能,并对吸水后样品进行了空间电荷分布的测定。
The thermal properties of ethylene propylene copolymer g acrylic acid ( EPM g AA ) and ethylene propylene copolymer g maleic anhydride ( EPM g MAH ) were investigated by using DSC. 用DSC研究了共聚聚丙烯-g-丙烯酸(EPM-g-AA)和共聚聚丙烯-g-马来酸酐(EPM-g-MAH)的热学性质。
C_9-acrylic acid ( C_9-AA ) water soluble petroleum resin with scale-inhibiting performance was synthesized by free radical copolymerization using C_9 fraction, the by-product from ethylene production, and acrylic acid as raw materials. 以乙烯生产过程中的副产物C9馏分和丙烯酸为原料,采用自由基溶液聚合,合成具有阻垢性能的C9-AA水溶性石油树脂。
