In order to clarify the relationship between the chemical structure of PAG (polyalkylene glycol) and the performance characteristics as the refrigeration lubricants used for HFC134a, performance tests were conducted using PAGs with different end groups and alkylene oxide chains in the presence of HFC134a.Newly developed dimethyl ether capped PAGs having more than 70 mol.% PO (propylene oxide) to less than 30 mol.% EO (ethylene oxide) as a monomer ratio were the most preferable of all PAGs tested. The refrigeration lubricants using these PAGs have been successfully introduced into the market for mobile air conditioning systems with refrigerant HFC134a.
