【摘要】 <正>降冰片烯(norbomene,NBE)加成聚合物具有极佳的光学性能(透光率≥92%、低双折射率)、低的介电常数、优异的抗离子蚀刻能力、低的吸湿性、耐化学品腐蚀以及良好的耐热性能,在微电子及光学领域具有广泛的用途,故近年来NBE乙烯基加成聚合催化剂的设计开发方兴更多还原

【Abstract】 Herein,two series of polynadimides with pendant linear alkyl and alicyclic groups have been prepared by addition polymerization of N-alkyl-exo-norbornene dicarboximides(nadimides;alkyl = propyl,butyl,pentyl,hexyl,cyclopropyl,cyclopentyl,cyclohexyl,and cycloheptyl) in the presence of novel naked palladium(Ⅱ) catalyst.The catalytic reactivity of the nadimides were discussed.The polynadimides with alicyclic groups present lower dielectric constants than those with linear alkyl groups.All resulting polynadimides exhibit better thermal stability than the unsubsitituted polynorbornenes.更多还原
