| Abstract: | To modify the structure of the resorcinol--formaldehyde（RF） arerogels, the reaction rules of resorcinol/hydroquinone,formaldehyde（RHF） system has been researched. The change of viscosity in the gelled process of RF and RHF has been online measured by supersonic viscosimeter. The dynamic rules of this composite system in different reaction conditions such as different reactants ratio and different catalyst concentrations. |
