Integrated process for the preparation of polycarbonate and/or polyarylate block copolymers with poly(aryl ethers)

A process for the preparation of poly(aryl ether) block copolymers with polycarbonates and/or polyarylates comprising the steps of a) reacting a hydroxy-terminated poly(aryl ether) with a high molecular weight aromatic polycarbonate, or a high molecular weight polyarylate, or a high molecular weight...

Beschreibung
Zusammenfassung:	A process for the preparation of poly(aryl ether) block copolymers with polycarbonates and/or polyarylates comprising the steps of a) reacting a hydroxy-terminated poly(aryl ether) with a high molecular weight aromatic polycarbonate, or a high molecular weight polyarylate, or a high molecular weight poly(arylatecarbonate) to yield a block copolymer; followed by b) coupling the material obtained in step a) under poly(aryl ether) forming conditions via the hydroxyl/activated dihalobenzenoid compound, or the hydroxyl/activated dinitrobenzenoid compound polycondensation process is described. The polymerization is preferably performed in an integrated manner starting with the poly(aryl ether)-forming monomers and using a polar aprotic solvent. Materials with an overall excellent combination of properties are obtained.
