摘要

Phosphorylation of poly(epichlorohydrin) (PECH) was successfully performed via reacting the P-H bond of 9,10-dihydro-oxa-10-phosphaphenanthrene-10-oxide (DOPO) with the pendent chloromethyl groups of PECH. From this reaction, phosphorus-containing PECH with hydroxyl terminal groups was obtained. This compound was further reacted with toluene-2,4-diisocyanate to form a phosphorous-containing polyurethane. The performance of the phosphorylation reaction and the structure of the resulting polymers were characterized by Fourier transform infrared spectroscopy, phosphorous-31 nuclear magnetic resonance (P-31 NMR) spectroscopy, and elemental analysis. The phosphorylated PECH and polyurethane were characterized by thermogravimetric analysis (TGA), which showed weight loss retardation behavior under air at high temperature at >500 degreesC and high char yield at 700 degreesC. Both of the synthesized polymers are potentially useful as multifunctional modifiers for epoxy resins and for improving the toughness and flame retardancy of the resins.
