Abstract
1, 3, 5,-Trimethyl-1, 1, 3, 5, 5-pentaphenyltrisiloxane has been prepared by the equilibration of 1, 3-dimethyl-1, 1,3, 3,-tetraphenyldisiloxane and methylphenylcyclosiloxanes in the presence of tetramethyl ammonium silanolate.By the repeated recycling of the by-products siloxanes, it was possible to obtain an overall yield of over 90%.The physical properties and the oxidative stability of 1, 3, 5-trimethyl 1, 1, 3, 5, 5-pentaphenyltrisiloxane were also determined.
