29Si NMR as a Tool for Studying Silicones

摘要: Abstract Compounds containing the Si—O—Si linkage are important both in geochemistry and for commercially produced materials. They occur a wide range of physical states; it is particularly common to find them as “pseudo-solids,” i.e., glasses, gels, rubbers, resins. Unfortunately, has not been easy obtain detailed information about molecular structure motion silicones. This partly due complexity many systems—for instance, typical silicone fluid contains species with various weights. Effects copolymerization, tacticity, cross-linking, segmental may complicate matters.
