silicon-containing aromatic diamines weresynthesized through amino-proteCtion by trimethylsilyl group
Wurtz coupling reaction and deprotction with overall yield of 25%.Copolymerization ofsilicon-containing aromatic diamines
aromatic diamines and tetracarboxylic aciddianhydrides was carried out and thermal analysis of corresponding poiymidesiloxanes was determined. The effect of Para and meta regioisomers on the thermalrelaxation behaviour in Tg transition was examined
which attributed to different conformation entropy in the structure of two regiosubstituted to different conformation entropy in the structure of two regiosubstituted moieties.
