METHODS AND COMPOUNDS FOR CONTROLLING THE MORPHOLOGY AND SHRINKAGE OF SILICA DERIVED FROM POLYOL-MODIFIED SILANES
摘要
<p>Siliceous materials are prepared by adding one or more additives, including water soluble polymers, and derivatives thereof, to sols containing tetraalkoxysilanes derived from polyols. The polymers facilitate phase separation of the growing silica gel matrix, leading to high surface area self-supporting silica gels with cure occurring at ambient temperatures. The materials also show a significant reduction in shrinkage properties.</p>
