High resolution silicon-29 NMR is used to study the microstructure of organosiloxane chain copolymers and three-dimensional cross-linked silicone resins. The signal splittings of the Si-29 NMR spectra of methy1-pheny1 siloxane copolymers have been assigned to monomer sequences up to the pentad level and the quantitative microstructure parameters have been estimated. It is shown that Si-29 NMR offers valuable information on the polymer framework of silicone resins both in the liquid and in the solid state.
