| 英文摘要 | polyimide btda-oda sample was prepared by polycondensation or step-growth polymerization method. its low temperature heat capacities were measured by an adiabatic calorimeter in the temperature range between 80 and 400 k. no thermal anomaly was found in this temperature range. a dsc experiment was conducted in the temperature region from 373 to 673 k. there was not phase change or decomposition phenomena in this temperature range. however two glass transitions were found at 420.16 and 564.38 k. corresponding heat capacity increments were 0.068 and 0.824 j g(-1) k-1, respectively. to study the decomposition characteristics of btda-oda, a tg experiment was carried out and it was found that this polyimide started to decompose at ca 673 k. |
