Synthesis, Characterization and Glass - Reinforced Composites of N,N'-Dimethylolthiourea – m-Aminophenol Resin
N,N’-Dimethylolthiourea (DMTU) resin having the methylol group ( –CH2 OH ) has been prepared and characterized. The condensation of DMTU resin with m-aminophenol was carried out in the presence of alcoholic alkali catalyst at varying ratios of DMTU: mAP, namely 1:1, 1:1.5 and 1:2. The resultant DMTU...

| description | N,N’-Dimethylolthiourea (DMTU) resin having the methylol group ( –CH2 OH ) has been prepared and characterized. The condensation of DMTU resin with m-aminophenol was carried out in the presence of alcoholic alkali catalyst at varying ratios of DMTU: mAP, namely 1:1, 1:1.5 and 1:2. The resultant DMTUmAP resin was characterized by elemental analysis, IR spectral studies, number average molecular weight (M¯n
) estimated by non-aqueous conductometric titration, and thermogravimetry. The curing study of DMTUmAP resin with hexamethylenetetramine (HMTA) was monitored by differential scanning calorimetry (DSC) and kinetic parameters were evaluated. Glass-reinforced composites based on the DMTUmAP-HMTA system have also been prepared and characterized. |
