| titleOfInvention | Aromatic polysulfone copolymer and its production |
| abstract | PURPOSE: To produce an aromatic polysulfone copolymer which can form a molding which is thermally stable, has a low water absorptivity and excellent mechanical properties and chemical resistance, and is transparent by forming a copolymer composed of randomly arranged polysulfone units and polyether sulfone units. n CONSTITUTION: An aromatic polysulfone copolymer composed of repeating units of formulas I and II and having a reduced viscosity (η red ) ≥0.1dl/g when measured in a 1g/dl solution in N,N-dimethylformamide at 25°C. It can be obtained by reacting compounds of formulas III and IV (wherein R and (l) are each an integer ≥0 and one of them is not 0; and M is an alkali metal atom) in a polar solvent or by reacting compounds of formulas V and VI (wherein R and (l) are each an integer ≥0 and one of them is not 0; and Y is H or an alkali metal atom) in a polar solvent in the presence of an alkali metal carbonate. n COPYRIGHT: (C)1991,JPO&Japio |
