Abstract:
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.
