三元共聚物合成的冷凝p-cresol (pci)和三聚氰胺与甲醛(F) (M) 2 M盐酸作为催化剂的存在与变化反应单体的摩尔比率。p-CMF-1的电气性能,p-CMF-2, p-CMF-3 p-CMF-4测量三元共聚物在广泛的温度(313 - 423 K)。从这些三元共聚物的导电性,激活能量电传导的评估和这些价值观在于范围6.36 x 10 - 20 - 8.23 x 10 - J / K。The plots of log  vs. 103/T are found to be linear over a wide range of temperature, which indicate that the Wilson’s exponential law  = oexp. (Ea/kT) is obeyed. On the basis of above studies, these terpolymers cab be ranked as semiconductors.
