Abstract:

The resolution enhancement technique of Fourier self-deconvolution is applied to the FT-IR spectra of linear polydimethylsiloxane oligomers. A series of pure oligomers of known chain length is analyzed in regions characteristic of silicon-methyl modes in order to separate dimethyl from trimethyl contributions. Once separated, the relative size of the deconvoluted peaks can be quantitatively related to the chain length of the oligomers. This proves to be an effective means of obtaining chain length information from the infrared spectra and is applicable to oligomers having molecular weights up to 15,000.
