Abstract
The reaction of the two model polyorganosiloxanes, QM(4) and Q(2)M(6), With ethanolic sodium hydroxide is reported (Q=SiO4/2 and M=Me(3)SiO( 1/2)). Removal of the M groups from QM(4) was rapid and led to the for mation of a sodium silicate species which was insoluble in organic sol vents. The reaction with Q(2)M(6), however, was incomplete and gave hy brid structures of the type Q(2)M(6-x)(O1/2Na)(x). A possible pathway for the formation of the sodium silicate species from QM(4) is propose d.
