键合剂1,1′-(1,3-苯二羰基)双-2-甲基氮丙啶的热行为

用DSC和TG－DTG等 过冷态和结晶态的键合剂1，1′－（1，3－苯二羰基）双－2－甲基氮丙啶（HX－752）的热行为，在－80℃－100℃范围内，除了过冷态在－37.6℃的玻璃化转变和结晶态在36.8℃－42.9℃的熔融外，没有任何其它物理化学。亚稳态的过冷液体比结晶态有较大的分解热。HX－752有复杂的分解过程，第一步分解失重虽小，但放热量很大，说明分子结构发生重大变化。

Thermal behavior of bonding agent 1,1′-(1,3-phenylenedlcarbonyl)bis-2-methyl-aziridine

The thermal behavior of either bulk-crystallized solid or super-cooled liquid of bonding agent 1,1'-(1,3-phenylenedlcarbonyl) bis-2-methyl-aziridine(HX-752)was investigated by DSC and TG-DTG. No physics and chemistry changes were found in the range of -80 ℃～100 ℃ except that the super-cooled liquid transform to the glass at -37.6 ℃ and the crystallized solid melt at 36.8 ℃～42.9 ℃.The decomposition heat for metastable super-cooled liquid is greater than that of crystallized solid. It is shown that thermal decomposition process of HX-752 is complicated although the mass-loss is relatively small, the release heat is great at the first step. It indicates that significant changes in the molecular constitution on the decomposition is happened.
