3,3-Bis(azidomethyl)oxetane and 3-azidomethyl-3-methyloxetane were obtained by bromination of pentaerythritol and metriol with a mixture of hydrobromic, acetic, and sulfuric acids, followed by cyclization in the presence of a phase-transfer catalyst TBAB, with the formation of oxetane ring and replacement of bromide substituents with azide ions. The copolymerization reaction of 3,3-bis-(azidomethyl)oxetane
3,3-双(叠氮基甲基)氧杂环丁烷和3-叠氮基甲基-3-甲基氧杂环丁烷是通过季戊四醇和间苯二酚与氢溴酸,乙酸和硫酸的混合物溴化,然后在相转移催化剂TBAB的存在下环化而获得的,形成氧杂环丁烷环并用叠氮化物离子取代溴化物取代基。3,3-双-(叠氮甲基)氧杂环丁烷和3-叠氮甲基-3-甲基氧杂环丁烷的共聚反应在由三异丁基铝和水制备的催化体系的存在下进行。使用小角度和广角X射线衍射分析方法确定合成共聚物的无定形晶体和畴结构。我们还提供了有关这些统计共聚物中构象和弛豫转变的数据。
