研究了实验室制备的两种导电聚苯胺材料与乙烯-丙烯酸共聚物（EAA）的共混及共混物的导电性能和微观形态。

Studied in this paper were the conductive properties and the microstructure of two blends of polyaniline with EAA, doped with ethylene-acrylic acid copolymer and DBSA respectively.

此外，通过红外表征测试表明交联PVC是通过马来酸酐和苯乙烯接枝到PV C主链上，然后与亚甲基二苯胺发生反应产生交联结构。

Furthermore, it was showed that maleic anhydride and styrene grafted the main chain of PVC, and then reaction with isocyanate formed cross-linked structure by FTIR.
