Abstract

Ethylene oxide and styrene oxide were sequentially polymerized to form the diblock copolymer E17S8 (E = oxyethylene, OCH2CH2; S = oxyphenylethylene, OCH2CH(C6H5); subscripts denote number-average block lengths in repeat units). Light scattering was used to investigate the properties of the micelles formed in dilute solution in the temperature range 15-30°C. The micelles are elongated (probably spheroidal) at the lower temperature and highly elongated (cylindrical, probably wormlike) at the higher temperature. Comparison with results reported for the copolymer E11B8 (B = oxybutylene, OCH2CH(C2H5)) allowed exploration of the effect of changing the hydrophobic block. The results provide useful indicators toward the design of ES copolymers with optimal solubilization properties. © 2003 Elsevier Science (USA). All rights reserved.
