Abstract: THE PRESENT INVENTION RELATES TO POLYARYLENE ETHER BLOCK COPOLYMERS OF THE COMMON FORMULA A-K-X-K-A, WHERE ?X- IS A POLYARYLENE ETHER SEGMENT HAVING A NUMBER-AVERAGE MOLECULAR WEIGHT OF AT LEAST 5,000 G/MOL, AND A- IS A SEGMENT OF THE GENERAL STRUCTURE R2NH-(R1-NH-CO-AR-CO-NH)N-R1-NH- WHERE R1 IS A LINEAR OR BRANCHED ALKYLENE GROUP HAVING 2 TO 12 CARBON ATOMS, AND AR IS AN ARYLENE GROUP HAVING 6 TO 18 CARBON ATOMS, R2 IS SELECTED FROM ARYLOYL, ALKYLOYL AND H, AND WHERE N IS OF A NUMBER-WEIGHTED AVERAGE OF 1 TO 3. EACH A IS BOUND TO X BY WAY OF A BINDING GROUP K OF THE STRUCTURE -CO-AR3-CO-, WHERE AR3 IS AN AROMATIC GROUP HAVING 6 TO 18 CARBON ATOMS. THE PRESENT INVENTION FURTHER RELATES TO A METHOD FOR PRODUCING THE POLYARYLENE ETHER BLOCK COPOLYMERS ACCORDING TO THE INVENTION, TO POLYMER COMPOSITIONS CONTAINING THE POLYARYLENE ETHER BLOCK COPOLYMERS ACCORDING TO THE INVENTION, AND TO THE USE THEREOF FOR PRODUCING MOLDED ARTICLES, FILMS, FIBERS OR FOAMS.

Abstract: THE PRESENT INVENTION RELATES TO A METHOD FOR PRODUCING POLY(ARYLENE ETHER) BLOCK COPOLYMERS, COMPRISING, IN A FIRST STEP, THE REACTION OF AT LEAST ONE AROMATIC DIHYDROXY COMPOUND COMPRISING 4,4?-DIHYDROXYBIPHENYL IN MOLAR EXCESS AND AT LEAST ONE AROMATIC DIHALOGEN COMPOUND TO FORM A POLY(BIPHENYL SULFONE) POLYMER, AND IN A SECOND STEP, THE REACTION OF THE POLY(BIPHENYL SULFONE) POLYMER WITH AT LEAST ONE AROMATIC DIHYDROXY COMPOUND AND AT LEAST ONE AROMATIC DIHALOGEN COMPOUND. THE INVENTION FURTHER RELATES TO THE POLY(ARYLENE SULFONE) BLOCK COPOLYMERS AND THE USE OF THE POTY(ARYLENE SULFONE) BLOCK COPOLYMERS TO PRODUCE MOLDED PARTS, FIBERS, FILMS, OR FOAMS.
