alpha,omega-Bis(heptamethylcyclotetrasiloxanyloxy)oligodimethylsilanes have
been synthesized by heterofunctional condensation of hydroxyheptamethylcyc
lotetrasiloxane with alpha,omega-dichloropermethyloligosilanes, Cl(Me2Si)(n
)Cl (n = 1-4, or 6). The substances are characterized by mass spectrometry,
Si-29-NMR, IR and UV spectroscopy. (C) 1999 Elsevier Science S.A. All righ
