Abstract: 
A new route for obtaining chemically pure and ecological polycarbonates has been developed. The process was carried out without any amines with dimethylosulfoxide (DMSO) as interfacial catalyst. It was established that DMSO was between 80–120 mol % to the quantities of applied monomers. Bisphenol A and bisphenol C [2,2-bis(p-hydroxyphenyl),-1,-1 dichloroethylene] were applied as bisphenolic monomers
