    Abstract: A phenol-modified polyorganosiloxane suitable as a modifier for an organic resin, in which a platinum metal content is reduced, and the yellowing is reduced, a method for preparing the same, and a modifier for an organic resin containing the same are provided. The phenol-modified polyorganosiloxane is a compound of formula (I), having a platinum metal content of 0.9 ppm or less. The phenol-modified polyorganosiloxane can be prepared by subjecting a phenol compound substituted with an alkenyl group of formula (IV) and a polyorganohydrogen siloxane of formula (V) to a hydrosilation reaction in the presence of a platinum-based catalyst applicable to a homogenous system, and subsequently, reducing the platinum metal content of the resulting product to 0.9 ppm or less by conducting one or more filtration procedures selected from the group consisting of filtration conducted where activated carbon is added, filtration conducted by using a filter comprising activated carbon, and filtration conducted by using a filter capable of adsorbing cations, alone or in combination.
