    摘要: 本文中利用次乙亞胺及其兩個甲基的衍生物可與三氯氧化磷反應形成變官能基離子型或三次乙亞胺基的化合物,這些含氮和磷的化合物擁有雙效官能基可以作為反應型阻燃劑及離子型PU架橋劑。在雙次乙亞胺基架橋劑行架橋反應後所保有的一個膦酸基,可被用來當作離子交換或離子架橋反應的官能基。利用粒徑分布與界達電位研究添加入架橋劑前後水性PU分散液的變化。在架橋反應或離子交換前後PU薄膜的物理及機械性質的研究包含了金屬含量、膠含量、水或酒精的吸收、抗張強度與伸長率等方面。而在PU薄膜的熱性質的探討是利用熱重分析儀、動態機械行為和測量其燃燒極限需氧指數(L.O.I.)等。
    Aziridine and its di-methyl substituted derivative reacted with phosphorus oxychloride and formed a di- functional ionic or a tri-aziridinyl compound. These nitrogen and phosphorus containing compound could have dual- function served as a reactive flame-retardant and cross- linker for PU ionomers. The phosphonic group of a di- aziridinyl curing agent after the curing reaction, it could function as a reactive site for ion exchange or ionic cross- linking. The particle size distribution and zeta potential of aqueous-based PU dispersions after the treatment of the curing agent were investigated. The physical and mechanical properties of PU films after the curing reactions or ion- exchanges were investigated, such as, metal content, gel content, water- or alcohol-uptake, tensile strength, elongation and etc.. The thermal properties of the cured PU films were also investigated by thermogravimetric analysis, dynamic mechanical behavior, and the measurement of limited oxygen index.
