Abstract:
1. A process for preparing a resin-linear organosiloxane block copolymer comprising: I) reacting in c) an organic solvent to form a resin-linear organosiloxane block copolymer; II) reacting the resin-linear organosiloxane block copolymer from step I) to crosslink the trisiloxy units of the resin-linear organosiloxane block copolymer sufficiently to increase the weight average molecular weight (M wherein the crosslinking reaction is promoted by a superbase, III) optionally, further processing the resin-linear organosiloxane block copolymer; and IV) optionally, removing the organic solvent.
