Cellulose‐ graft ‐poly(ethylene glycol) copolymers were synthesized, and the thermal properties of the copolymers were investigated. The cellulose‐ graft ‐poly(ethylene glycol) copolymers showed solid–solid phase‐transition behavior with a high thermal storage density and good thermal stability in the temperature region of 25–250°C. The phase‐transition temperature and enthalpy of the cellulose‐ graft ‐poly(ethylene glycol) copolymers could be adjusted through changes in the poly(ethylene glycol) content. The prepared copolymers could be used as thermal energy storage materials. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
