Abstract
The disclosed organo-polysiloxane derivative is useful as a dispersing agent for homogeneously dispersing a silicone gel in a curable resin such as an epoxy resin. The organo-polysiloxane derivative is prepared by first reacting an organo-polysiloxane compound A having an active hydrogen-containing group in each of its both terminals and having from 5 to 70 siloxane bonds with a bifunctional organic compound B having two functional groups reactable with active hydrogen. The reaction mixture obtained in the first reaction is reacted with a mixture of a bifunctional organic compound C having two active hydrogens and a bifunctional organic compound D having two functional groups reactable with the active hydrogen.
