Preparation,Characterization,and Compatison of Thermal Properties of Aromatic Polyether Imides
摘要
Abstract
Two aromatic polyimides were prepared by twostep way.Firstly,the poly (amic acid) s were synthesized from 1,3-bis(4-amiaophenoxy)benzene and two difierent aromatic dianhydrides.Secondly,polyimides were prepared via thermal imidization of poly(amic acid) precursors.The polyimides prepared were insoluble in cammon organic solvents such as tetrahydrofuran,chloroform and N,Ndimethylformamide.The inherent viscosities of poly(amic acid)s were 1.82 dL/g and 2.67 dL/g.The high inherent viscosities were due to the strong intra-or intermoleeular hydrogen interaction.The polyimides were characterized by mechanical and thermal analysis.It was found that the samples are of excellent thermal stability,higher glasstransition temperature and excellent dynamic mechanical andthermal properties.关键词
