<p>The present invention relates to the technical field of organic-inorganic nano hybrid materials. Disclosed is a preparation method of cubic octamethyl acryloyloxy silsesquioxane crystals, the method comprising the following steps: (1) preparing the hydrolysate ofγ-methacryloyloxy propyltrimethoxy silane by mixing theγ-methacryloyloxy propyltrimethoxy silane, a polar solution, and a catalyst A, conducting magnetic stirring, removing the solvent, washing until neutral, dehydrating, and filtering; (2) preparing a recondensation product of theγ-methacryloyloxy propyltrimethoxy silane by dissolving the product of step (1), adding by drops catalyst B, conducting a nitrogen gas protection reaction, washing until neutral, drying, filtering, and removing methylbenzene; (3) preparing the cubic octamethyl acryloyloxy silsesquioxane crystals by adding a crystal nucleus to the product obtained in step (2), separating out and isolating the crystals, thus yielding the cubic octamethyl acryloyloxy silsesquioxane crystals.</p> |
