The reaction between a dihydroxyphenoxycyclotriphosphazene containing allylic functions, 3, and hexamethylene‐1,6‐diisocyanate (HDI) leads to a new cyclotriphosphazene‐substituted polyurethane 4. The structures of both classes of compounds involved in that synthesis were investigated by 31 P‐, 13 C‐, and 1 H‐NMR, infrared, and mass spectrometries, size‐exclusion chromatography, and elemental analysis. The thermal behavior of 4 was investigated and compared to that of hexaphenoxycyclotriphosphazene, N 3 P 3 (OC 6 H 5 ) 6 , and of a polyurethane synthesized from 1,3‐bis(hydroxy)benzene and HDI. The free‐radical‐promoted grafting of 4 onto the polyethylene surface is described. The resultant surface was studied by ATR–IR, XPS, and contact‐angle techniques. © 2003 Wiley Periodicals, Inc.
