Abstract

AbstractA 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 (Tg) and thermal decomposition temperature (Td5%) of PEO higher. When the content of MPF is 2%, the Td5% of MPF/PEO is 346°C, which is much higher than that of pure PEO (240°C). When the content of MPF is 50%, Tg of PEO is up to 26°C, which is 90°C higher than that of pure PEO.
