An asymmetrically substituted polyorganosiloxane comprising at least one or more siloxane blocks and different reactive groups at each end of the siloxane chain, e.g. an alkoxysilyl, alkenyl, epoxy, hydroxyaromatic or an ionic substituent. Each polyorganosiloxane block has substantially a monomodal chain length distribution and is suitable for the use as a surface modifying agent for organic or inorganic particles, as a surface active material, and/or as a compatibilizer in compositions having more two or more non-miscible phases.
