This study outlines a method for preparing a complex involving glycoluril and melamine (GU-ME). The structure of the resultant complex was analyzed using IR and NMR spectroscopy. In the subsequent phase, the polymer GUMEFA was derived from the resultant complex, employing hydroxyethylidene diphosphonic acid (HEDP) as a sustainable plasticizer, with a proposed chemical mechanism for its formation. The molecular weight of the resulting GUMEFA was analyzed, and the formation chemistry was proposed. GUMEFA was characterized, and its free formaldehyde and methylol group contents were investigated. It was observed that GUMEFA prepared with HEDP contained approximately 1.15-1.34 wt.% free formaldehyde and 1.56-0.54 wt.% methylol groups. These findings provide valuable insights for developing resins of different compositions and applications, thereby paving the way for producing composite materials with tailored properties.
本研究概述了一种制备包含甘脲和三聚氰胺(GU-ME)的配合物的方法。使用红外光谱和核磁共振光谱对所得配合物的结构进行了分析。在随后的阶段,以羟基亚乙基二膦酸(HEDP)作为可持续增塑剂,从所得配合物中衍生出聚合物GUMEFA,并提出了其形成的化学机理。分析了所得GUMEFA的分子量,并提出了形成化学过程。对GUMEFA进行了表征,并研究了其游离甲醛和羟甲基含量。观察到用HEDP制备的GUMEFA含有约1.15-1.34 wt.%的游离甲醛和1.56-0.54 wt.%的羟甲基。这些发现为开发不同组成和应用的树脂提供了有价值的见解,从而为生产具有定制性能的复合材料铺平了道路。
