Bis(p-allyloxyphenyl)polydimethylsiloxanes were synthesized by equilibrium polymerization of octamethylcyclotetrasiloxane (D4) with 1,3-bis(p-allyloxyphenyl)-l,l,3,3-tetramethyldisiloxane in the presence of a base catalyst (Bu4NOH). Cleavage of allyl groups from these polysiloxanes was performed by the use of palladium (II) catalyst and diethylamine, forming ~,~o-bis(p-hydroxyphenyi)polydimethylsiloxanes in good yields.
