In 2019,Materials Today: Proceedings included an article by Zou, Faxing; Chen, Shaojun. Safety of 2,6-Diaminopyridine. The article was titled 《A Novel 2,6-Diaminopyridine-base Polymer with Thermo-/Water-responsive Shape Memory Effect》. The information in the text is summarized as follows:
Shape memory polymers with multiple stimuli have obtained increasing attention. This study illustrates a strategy for synthesizing polymers with thermo-/water-responsive shape memory effect. The novel polymer with excellent nature was proved to synthesized correctly using 2,6-diaminopyridine (DAP), polyethylene glycol (PEG1000) and hexamethylene diisocyanate (HDI). The result shows that the thermal stability of polyurethane can be improved with increasing of the DAP, embed into mol. chain. Moreover, the polymer which possesses excellent thermo-responsive, can be deformed and restored when in contact with water. The finding in this contribution, strongly promote diversified applications of shape-memory polymers, especially in engineering fields. The results came from multiple reactions, including the reaction of 2,6-Diaminopyridine(cas: 141-86-6Safety of 2,6-Diaminopyridine)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Safety of 2,6-Diaminopyridine
