| Abstract | ||
| This study concern kinetic reactions of phenol-resorcinol-formaldehyde and compare to kinetic reaction of the polymer phenol- resorcinol-formaldehyde. The rate of reactions were followed through concentration variation as a function of time using hydroxylamine chloride at pH 4.12 . The result shows that the rate of polymer reaction increase with increasing of resorcinol concentration. This is due to presence of two hydroxyl which increase the electron density on the aromatic ring compared to phenol which contains only one active group . In additions, the product has high glass transition which can be used as a temperature insulator. | ||
