## Abstract The behavior of oxyethylene‐oxypropylene block copolymers (OEOPBC) of EPE type was investigated. Most of the investigations were performed with OEOPBC having 30 oxypropylene subunits and different lengths of oxyethylene chain. The dependences of the peak height on the concentration of s
