Abstract
The polymerization of silicic acid has been investigated at a pH of 8.5 and initial monomer concentration of 300 p.p.m. The rate of polymerization was determined at 25, 30, 35, 40 and 45°C so that the activation energies could be calculated. The activation energies were found to be −16±4 kcal/mole in the 25–35°C region and 14±4 kcal/mole in the 35–40°C region. The negative activation energy is explained by assuming a pre-equilibrium step involving a hydrogen bonded species. The thermodynamic parameters were also determined for the polymerization process. A mechanism has been proposed for the polymerization reaction.
