The measurement of the temperature dependences of PVME integrated intensities permitted to determine the influence of polymer concentration and ethanol content in D2O/EtOH mixture on the phase transition. It was found that the transition region was shifted to lower temperatures with increasing polymer concentration, probably due to the preferred polymer–polymer contacts in more concentrated solutions.
