Among the many analytical methods used for silicones,10 only a few are presented here.
Composition can easily be analysed by chromatography. This allows quantifying the low molecular weight oligomers present
in silicone polymers. As mentioned above, (see Polymerisation and polycondensation), polymerisation reactions lead to the
formation of two molecular weight distributions, cyclics around a degree of polymerisation y and polymers around a degree of polymerisation z:
