    • A conducting polymer composite comprising: (i) a phase I material consisting essentially of a polymer copolymer of ethylene and an unsaturated ester having 4 to 20 carbon atoms, said copolymer having a crystallinity of 0 to about 30 percent as determined by differential scanning calorimetry analysis and having a melt viscosity η I ; (ii) a phase II material having a crystallinity of 0 to about 30 percent as determined by differential scanning calorimetry analysis and having a melt viscosity of η II , said phase II material consisting essentially of (A) a non-polar copolymer of ethylene, an alpha-olefin having 3 to 12 carbon atoms, and, optionally, a diene, or (B) a non-polar elastomer, either of which, when mixed with phase I material, will not enter into a completely homogeneous state, but is compatible with the phase I material; and (iii) a conducting filler material dispersed in the phase I material and/or the phase II in an amount sufficient to be equal to or greater than the amount required to generate a continuous conducting network in the phase I and phase II materials, with the proviso that the phase I and phase II materials, in the molten state, have the following relationship: (η I ÷η II )x(V II ÷V I )=0.5 to 2.0 wherein V I and V II are the volume fractions of the phase I and phase II materials, respectively, and V I +V II =1.
    • 一种导电聚合物复合材料,其包含:(i)基本上由乙烯和具有4至20个碳原子的不饱和酯的聚合物共聚物组成的相I材料,所述共聚物通过差示扫描量热法分析测定的结晶度为0至约30% 并具有熔体粘度ηI; (ii)通过差示扫描量热分析测定的具有0至约30%的结晶度的II相材料,其熔体粘度为ηII,所述II相材料基本上由(A)乙烯的非极性共聚物, 具有3至12个碳原子的α-烯烃,和任选的二烯,或(B)非极性弹性体,当与I相材料混合时,它们不会进入完全均匀的状态,而是相容的 与I相材料; 和(iii)分散在I相材料和/或II相中的导电填料,其量足以等于或大于在I相和II相材料中产生连续导电网络所需的量, 条件是熔融状态下的相I和相II材料具有以下关系:(ηI÷ηII)x(VII÷VI)= 0.5至2.0其中VI和VII是相I和相的体积分数 II材料,VI + VII = 1。
