A novel phenolic resin (phenolic containing diphenyl oxide [named by MPF ]) was synthesized and blended with poly(ethylene oxide) ( PEO ). In modified PEO , the shear‐thinning behavior appears and shortage modulus ( G ′) deviates from classic terminal behavior. Compared with PEO , there is an increase in the nucleation rate and a decrease in the growth rate of spherulites in modified PEO . A small amount of MPF plays a role of the nucleating agent of PEO . The addition of MPF into PEO makes the glass transition temperature ( T g ) and thermal decomposition temperature ( T d5% ) of PEO higher. When the content of MPF is 2%, the T d5% of MPF / PEO is 346°C, which is much higher than that of pure PEO (240°C). When the content of MPF is 50%, T g of PEO is up to 26°C, which is 90°C higher than that of pure PEO .
