摘要：
The small-angle neutron scattering study of spherical and wormlike micelles formed by poly(oxyethylene)-based diblock copolymers was discussed. Results showed that the diblock E4B10 formed spherical micelles with a poly(oxybutylene) core over a temperature range of 20 to 60°C. Wormlike micelles were formed at 60° and spherical micelles below 40°. The transition to wormlike micelles was ascribed to a decrease in the coverage of the core by the polyoxyethylene chains at high temperatures.
