Abstract

2,2,4,4,6,6-Hexachlorocyclotriphosphazene was modified by nucleophilic substitution to obtain building blocks for organic polymers and siloxane networks. 2,2,4,4,6,6-Hexachlorocyclotriphosphazene was substituted with functional groups to enable atom transfer radical polymerization (ATRP) as well as silicon alkoxide as precursors for the sol-gel process. ATRP was carried out with methyl acrylate followed by a chain extension with iso-bornyl acrylate to obtain new thermoplastic elastomers. The sol-gel process was carried out with acid, base and fluoride catalysts and the resulting materials were compared by TGA and DSC measurements.
