摘要：

The clouding phenomenon of aqueous solutions of POE-POP-POE triblockcopolymers was investigated by infrared and Raman spectroscopy. Near the cloud point discontinuities in band intensities were observed. By the use of the quantum chemical PCILO method conformational energies of model POE molecules and of model POE-water associates were calculated. A conformational transition model is suggested for the clouding. © 1990.
