Abstract
Provided are polyorganosilsesquioxane and process for preparing the same. The polyorganosilsesquioxane is obtained by various methods including polymerization of 1,3-diorganosiloxane, a precursor that is prepared by using silane compounds as starting materials. The polyorganosilsesquioxane has convenience in handling and controlling the rate of polymerization, and structure of highly regular form, and be imparted high functionality and various characteristics as compared to a conventional polyorganosilsesquioxane.
