Process for producing low density gel compositions |
摘要 |
Processes for producing gel compositions comprising: esterifying a portion of the surface of a gel composition sufficient to produce a gel composition having a rod density of less than or equal to 0.15 g/cc, and/or a tap density of less than or equal to 0.2 g/cc through contact with at least one esterification agent and at least one catalyst. The processes may be utilized to produce low density gel compositions without the need for a supercritical drying step or thermal treatment.
