Abstract
Scanning calorimetric data obtained for the investigation of phase separati on in dilute aqueous solutions of a propylene oxide (PO) and ethylene oxide (EO) block copolymer (PO)(27)(EO)(4)(PO)(27) are presented, The results ar e consistent with those captured for other PO containing block copolymers a nd homopolymers and indicate that phase separation occurs as a result of th e dehydration and subsequent interaction of the PO blocks in solution.
