ABSTRACT:
An organopolysiloxane having monofunctional siloxane units (M unit) and tetrafunctional siloxane units (Q unit) and also having in the molecule an epoxy group-containing organic group, a polydiorganosiloxane residue bonded therein across a divalent hydrocarbon group, and optionally alkoxysilylalkyl is useful as an internal stress-relaxing agent, an internal mold-release, and as an adhesion promoter for curable organopolysiloxanes. These organopolysiloxanes are made by an addition reaction.
