Notes:
An exhaustive end-capping method for the analysis of silicone copolymers and networks using hexamethyldisiloxane in the presence of trifluoromethanesulfonic acid was demonstrated. The hard block of a polymide-co-polysiloxane was isolated by the equilibration of the copolymer with a large excess of hexamethyldisiloxane and subsequently examined by size exclusion chromatography. Addition cured polyimidesiloxane networks were also equilibrated with an excess of the disiloxane and the resulting oligmoers characterized by gas chromatography of the end-capped fragments.
