Abstract

A series of polyurethane hybrid networks have been synthesized using octakis(m-isoprenyl-α,α′-dimethylbenzylisocyanato dimethylsiloxy) octasilsesquioxane (Q₈M₈^TMI) as a crosslinking agent. The formation of the urethane linkages within the polyurethane hybrids was confirmed by photoacoustic FTIR spectroscopy. The TGA and DSC studies demonstrated that the incorporation of the POSS crosslinking agents altered the thermal properties of the polyurethanes, and that this was dependent on the length of the polyethylene glycol chain.
