Researching into tg - dt diagrams , we have concluded as follows : the initial decomposition temperature ( idct ) of polymer ( i ) is 220c and the first lost group ( flg ) ls carboxide ; the idct of polymer ( hi ) is 194cand the flg is - nh ; so the pyrolysis mechanisms of the two polymers are different 對聚合物( d和聚合物( l11 )的tg一ot研究表明:聚合物( d的開始分解溫度為220 ,失去的第一個基團為> c = 0 ;聚合物( 11工)的開始分解溫度為! 94oc ,先失基團為一陽,兩者的熱解機理不盡相同。

In all those complexes , no matter which conformation ida assumes ( mer - or fac - style ) , the two 0 atoms of 1n2o are both from carboxylic hydroxyl . however , by comparing the bond length , we can find that o ( 4 ) and o ( 2 ) atom is from different group in this complex , 0 ( 4 ) atom from carboxylic hydroxyl , whereas , 0 ( 2 ) from carboxylic carboxide 值得注意的是:在這個雙核配合物中,我們首次發現一種新穎的配位方式: ida上與金屬離子配位的三齒螯合原子是亞氨n原子、一個羧基上的羥基o原子和另外一個羧基上的羰基o原子。
