The solubility of methylol urea in water was obtained by mixing 1 ml of the resin with 5ml of distilled water at room temperature (30[degrees]C).
Figure 1 shows the effect of viscosity on the melting point of methylol urea.
This experiment examined the effect of viscosity on some physical properties of methylol urea synthesized through the OSP synthetic route.
