SYNTHESIS AND CURING BEHAVIOR OF5 (6)-AMINO-1-(4-AMINOPHENYL)-1,3,3-TRIMETHYLINDANE
摘要
Abstract
5(6)-amino-l-(4-aminophenyl)-l ,3,3-trimethylindane(PIDA) was obtained by the reaction of nitration and reduction from 1,3 ,3-trimethyl-l-phenylindan, the structure was characterized by FTIR, 'H-NMR and LC-MS. The curing behaviors of system were composed of this new curing agent and E-44 epoxy resin were studied by means of DSC. The apparent activation energy of E-44/PIDA caculated by Kissinger and Ozawa methods were 56. 48kJ/mol and 60. 76kJ/mol respectively, and the curing reaction order calculated by Crane formula was 0. 88. These results show that contrast with DDS, PIDA can reduce the curing temperature and curing time, it can also improve the heat resistance of the composite material because of its low melting point and indane ring structure. The glass transition temperature Tg and initial decomposition temperature Td are 167. 8℃ and 361. 71 °C respectively.关键词
