Abstract
An organopolysiloxane containing at least one epoxy group is produced by heating a mixture of (a) an epoxy group-containing organosiloxane; (b) an organosiloxane lacking an epoxy group and optionally containing an arkenyl group; (c) an aprotic polar organic solvent; and (d) a basic catalyst, until reaction between (a) and (b) by a disproportionation equilibration reaction occurs.
