Summary: | Copolycondensate molding materials are obtainable by polycondensation of from 2 to 98 mol % of 2,2-di-(4'-hydroxyphenyl)-propane (A), from 2 to 98 mole % of 4,4'-dihydroxydiphenyl sulfone (B) and from 0 to 96 mole % of (C) (* CHEMICAL STRUCTURE *) where R1 and R2 are each H, C1-C6-alkyl or C1-C6-alkoxy, X is a chemical bond, -S-, -O-, -CO-, CR3R4 (where R3 and R4 are different when n and p are each 0), or SO2- only when n or p is (+ not +) 0), R3 and R4 are each H, C1-C6-alkyl, C1-C6-alkoxy, aryl or halogen-substituted alkyl of 1 to 4 carbon atoms, m is 0 or 1, and n and p are each 0, 1, 2, 3, or 4, with from 1 to 100 mole % of (D) (* CHEMICAL STRUCTURE *) where R5 and R6 have the same meaning as R1 and R2, and v and w are each 0, 1, 2, 3 or 4, and from 0 to 99 mol % of (E) (* CHEMICAL STRUCTURE *) where R7-R10 are each Cl or F or have the same meanings as R1 and R2, q is 0 or 1, r, s, t and n are each 0, 1, 2, 3 or 4, Z1 is -SO2- or -CO- and Z2 is -O-, -S-, -SO2-, -CO- or a chemical bond, with the proviso that one or more of the components C and E are present and the molar ratio of B to the sum of A and C is not greater than 1. |
