    摘要: A process is disclosed for preparing a resin-linear organosiloxane block copolymer by reacting in a first step an endcapped linear organosiloxane and an organosiloxane resin to form a resin-linear organosiloxane block copolymer. The resulting resin-linear organosiloxane block copolymer is then crosslinked in a second step to sufficiently increase the average molecular weight of the resin-linear organosiloxane block copolymer by at least 50%. The resin-linear organosiloxanes block copolymers prepared by the disclosed process may provide optically solid compositions which may be considered as “reprocessable”.
