ABSTRACT:
A method for modifying poly(ethylene oxide) by grafting polar vinyl monomers, such as poly(ethylene glycol) methacrylates and 2-hydroxyethyl methacrylate, onto the poly(ethylene oxide) is disclosed. The grafting is accomplished by mixing the poly(ethylene oxide), the monomer(s) and an initiator and applying heat. Preferably, the method is a reactive-extrusion process. The resulting modified poly(ethylene oxide) has improved melt processability and may be used to thermally process articles which have improved properties over articles similarly processed from unmodified poly(ethylene oxide).
