Novel poly(2-(3-sulfo)benzoyl-1,4-phenylene)-block-polynaphthalimide (PSP-b-PI) copolymers were successfully synthesized by Ni(0)-catalyzed copolymerization of 2,5-dichloro-3'-sulfo-benzophenone and dichloro-terminated naphthalimide oligomer. The membranes exhibited a microphase-separated structure and good hydrolytic stability at 130 °C. They showed a fairly strong anisotropy of membrane swelling with much smaller in-plane swelling, but a rather weak anisotropy of proton conductivity. The membranes had a fairly high through-plane conductivity in water and even under low relative humidity. The PSP-b-PI copolymer with an IEC of 1.5 meq · g(-1) showed high PEFC performance due to the high through-plane conductivity.
通过镍（0）催化2,5-二氯-3'-磺基二苯甲酮与二氯封端的萘酰亚胺低聚物的共聚反应，成功合成了新型聚（2-（3-磺基）苯甲酰基-1,4-亚苯基）-嵌段-聚萘酰亚胺（PSP-b-PI）共聚物。这些膜呈现出微相分离结构，在130°C下具有良好的水解稳定性。它们表现出相当强的膜溶胀各向异性，面内溶胀小得多，但质子传导率的各向异性较弱。这些膜在水中甚至在低相对湿度下都具有相当高的面内电导率。离子交换容量为1.5 meq·g(-1)的PSP-b-PI共聚物由于高面内电导率而表现出高的质子交换膜燃料电池性能。
