Ethylene oxide and 1,2-butylene oxide were sequentially polymerised to form the diblock copolymer E13B10 (E=oxyethylene, B=oxybutylene, subscripts denote number-average block lengths in repeat units). Dynamic and static light scattering over the temperature range 10-30 degrees C demonstrated a transition from

A new soluble cyclodextrin derivative 6-O-(2-hydroxybutyl)-beta-cyclodextrin (6-HB-beta-CD) was prepared. Its molecular binding and recognition ability were investigated with the comparison of beta-cyclodextrin (beta-CD), 2-O-(2-hydroxypropyl)-beta-cyclodextrin (2-HP-beta-CD), 6-O-(2-hydroxypropyl)-beta-cyclodextrin (6-HP-beta-CD), and 2-O-(2-hydroxybutyl)-beta-cyclodextrin (2-HB-beta-CD). The relationship between the complex stability constants and the possible
