Synthesis and Characterization of Nanocomposites Based on Copolymers of POSS-ONDI Macromonomer and TFONDI: Effect of POSS on Thermal, Microstructure and Morphological Properties.
Polyhedral oligomeric silsesquioxanes (POSS) possessing 7-oxanorbornene-5, 6-dicarboximide (POSS-ONDI) functionalized macromers are synthesised and well characterized using FT-IR, 1H, 13C and 29Si-NMR spectroscopic techniques. The homopolymer of [N-3(trifluoromethyl)phenyl-7-oxanorbornene-5,6-dicarboximide] (TFONDI) and a series of linear copolymers between [N-(POSS)-7-oxanorbornene-5, 6-dicarboximide] POSS-ONDI and TFONDI are prepared through ring opening metathesis polymerisation (ROMP) using Grubbs catalyst. All the polymers are characterized using FT-IR, 1H-NMR, TGA, DSC, AFM, TEM, XRD and GPC techniques.
