(57) [Summary] [Objective] To provide a method for efficiently reducing the amount of a volatile low-molecular-weight organosiloxane contained in an equilibrium-polymerized organopolysiloxane under mild conditions to purify the organopolysiloxane. . [Structure] A low molecular weight organosiloxane contained in an organopolysiloxane equilibrium-polymerized with an acidic or basic polymerization catalyst is a porous inorganic powder having an average pore size of 1 to 5,000 Å (for example, porous silica powder, porous A method for purifying organopolysiloxane, which comprises adsorbing and removing alumina powder, porous aluminosilicate powder, and porous glass powder). |
