<p>The present invention relastes to fluorine free polymeric oil-return agents that increase the miscibility of lubricants such as mineral oils and/or oxygenated lubricants with refrigerants in order to improve oil return and system performance of refrigeration systems. It was discovered that fluorine free block copolymers having a block compatible with the oil phase, and at least one block compatible with the refrigerant phase can effectively compatibilize lubricanting oils with HFC and HFO refrigerants.</p>
