    摘要: Polycarbonates are provided based on aromatic bis-hydroxy compounds which contain s-triazine compounds as linking members between 2 mols of the aromatic bis-hydroxy compounds bonded in each case via an oxygen atom thereof, on the one hand, and via carbon atoms of the s-triazine ring, on the other, the s-triazine rings carrying, on at least one further carbon atom, organic radicals with functional groups, these radicals being bonded via oxygen, nitrogen or sulphur. The novel polycarbonates may be used as selective solvents for hydrocarbons mixed with water or for making resins or coatings.
