叔丁基二胺的合成及其扩链双马来酰亚胺的应用研究

用叔丁基对苯二酚和对氯硝基苯反应,合成了1,4-双(4-硝基苯氧基)-2-叔丁基苯(BNTB),用水合肼还原后得到叔丁基二胺单体1,4-双(4-氨基苯氧基)-2-叔丁基苯(BATB).用BATB与双酚A二酐反应,以马来酸酐作为封端剂,得到了链中含酰亚胺环的内扩链双马来酰亚胺,齐聚物的分子量控制为7 172 g/molo将所得的双马来酰亚胺固体粉末溶于极性溶剂后,直接涂覆铜箔形成20μm涂层、干燥,再经程序升温固化后获得无胶型挠性覆铜板.并对其进行了分析测试,结果表明,所得到的二层法挠性覆铜板(2L-FCCL)具有优异的耐热性、尺寸稳定性和低吸水率.

Preparation of Tert-butyl Diamine and Applied Research of Maleimide-terminated Oligomer

2-tert-butyl-1,4-benzenediol was reacted with p-choronitrobenzene and 1,4-bis(4-nitrophenyloxy)-2-tert-butylbenzene(BNTB) was synthesized.Then BNTB was reduced with hydrazine hydrate;and a novel diamine monomer 1,4-bis(4-aminophenoxy)-2-tert-butylbenzene(BATB) was gained.Maleimide-terminated polyimide oligomer was synthesized from BATB and 2,2'-bis4-(3,4-dicarboxyphenoxy) phenyl]propane dianhydride(BPADA).The molecular weights of soluble aromatic imide oligomers were successfully controlled at 7 172 g/mol....
