## Abstract Blends of poly(vinyl alcohol) (PVAI) with poly(ethyleneimine) (PEI) were prepared by casting from a common solvent. All blends show a single, composition dependent glass transition temperature (__T__~g~), indicating that the blends are miscible in the amorphous state and in the melt. Th
Triethoxysilane HSi(OEt) 3 was used as coupling agent to graft a poly(organophosphazene) (POPZ) containing allylic functions to the surface of poly(vinyl alcohol) or poly(ethylene-co-vinyl alcohol) films. Hydrolyzed HSi(OEt) 3 , which contained both inorganic (Si-OH) and organic (Si-H) reactivities,
