Synthesis and Characterization of Novel Phosphorous-Coupling Agent for Use as Compatibilizer, Flame Retardant, Hardener and Adhesion Promoter in Making Polymer Networks

A new phosphorous containing coupling agent namely, diethylenetriamino-diethylphosphate (DTDP) was synthesized. The structure was confirmed by means of FT-IR, H-1-NMR, C-13-NMR spectra, and mass spectral analysis. The coupling ability of DTDP was investigated by blending it with DGEBA and PDMS, and thus obtained blends have reflected in an increase in the modulus, glass transition temperature and adhesion strength property between the metal-to-metal interface. The high thermal stability, IPDT temperature and flame retardant properties (LOI) were attributed to the presence of phosphorous atom in the coupling agent.
