A~traet--Aqueous solutions of hydroxyl-terminated triblock copolymers of ethylene and propylene oxides display turbidity, both on heating and cooling. The lower critical solution temperatures increase with increase in the content of ethylene oxide units. Phase diagrams obtained with acetyl-terminate
