Abstract 1. Colloidal silica can be partially or completely removed from filled rubber stocks by boiling in 1% aqueous NaOH. 2. Degree and rate of extracting directly depend on the reinforcing effect of the silica. The higher the filler activity, the more complete its extractability from the rubber. Inactive samples of silica practically cannot be extracted from filled rubber stocks. 3. The active silica forms a thixotropic chain structure in the rubber, but inactive silica is distributed in rubber as isolated particles or aggregates. 4. The rubber portion that remains after extraction of the active silica is insoluble in common rubber solvents. 5. The equilibrium swelling value in binary solvents (butanol-toluene) is lower, the higher the reinforcing action of the silica. 6. The reinforcing effect of silica is proportional to its moisture takeup capacity, which may be determined by a simple method described. 7. Based on the experiments described, the type of linkages involved and the structure of the rubber stock filled with silica are considered.
