Application of 29Si NMR spectroscopy in organosilicon polymers' investigations

Polimery 2007, No 10, 730


Summary

A short review of applications of modern 29Si NMR techniques in the investigations of silicon based polymeric materials is presented. Two variants of investigations i.e. in liquid state and solid-state NMR were taken into account. The first one is used for characteristics and identification of the products (polysiloxanes, polysilanes) as well as for fine investigations of the structure and dynamics of polymer chain and mechanism and kinetics of polymerization reactions. Solid-state NMR is used for the evaluation of orientation, dynamics and conformational changes of polymer chains inside or on the surface of organosilicon material.


Key words: 29Si NMR spectroscopy, organosilicon polymers, solutions, solid state, structure
