The original crystal configuration of KGM was destroyed, and the molecular structure was disordered. The glass transition temperature T(subscript g of TKGM was only 13.14℃, and there's an obvious melting decalescence peak at 102℃, the difference between decomposed temperature and melting temperature is above 200℃. This means that TKGM has a good thermoplasticization property.
