Different molar ratios of melamine and formaldehyde were used to synthesize the corresponding resins. The prepared resin samples were characterized by using molecular weight determination viscometry and thermogravimetric analysis (TGA). The maximum percentage of solid content (69.7) was obtained at pH 8.5 and 75°C temperature. The molecular weight of MF resin was increased with an increase of melamine monomer concentration. The highest residual weight 14.125 wt. was obtained with sample 10. © 2014 Sami Ullah et al. publisher: Hindawi Publishing Corporation date: 2014 type: Article type: PeerReviewed identifier: Ullah, S. and Bustam, M.A. and Nadeem, M. and Naz, M.Y. and Tan, W.L. and Shariff, A.M.
