Abstract
A method of preparing an organopolysiloxane is provided. An organopolysiloxane, which has both a linear or cross-linking structure derived from a trifunctional siloxane unit and a linear structure derived from a difunctional siloxane unit among the molecular structures and also has a sufficiently long linear structure, can be effectively prepared. Also, the organopolysiloxane can be synthesized so that it can have a sufficiently high molecular weight, and a target product showing excellent physical properties can be effectively prepared by minimizing a ratio of a functional group such as an alkoxy group or a hydroxyl group in the synthesized organopolysiloxane.
