Abstract
A composition for viscous fluid coupling is described. The composition comprises a liquid organopolysiloxane and a reaction product of a liquid organopolysiloxane with an aromatic aminophenol in the presence of a quaternary phosphonium hydroxide. The composition is characterized by a long term stability, undergoing little torque variation even at elevated temperatures and high shear forces.
