Abstract
An aromatic polysulfone composition is provided which includes an aromatic polysulfone and an organic compound having a boiling point no lower than 100° C. and no higher than 400° C. The organic compound is contained in an amount of at least 0.1 ppm and at most 10 mass % relative to the mass of the aromatic polysulfone. The aromatic polysulfone has repeating units expressed by formula (1): -Ph1-SO2-Ph2-O— (1) In formula (1), Ph1 and Ph2 represent phenylene groups in which one or more hydrogen atoms that bind to the phenylene groups may, independently of each other, be substituted with an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 20 carbon atoms, or a halogen atom.
Claims5
An aromatic polysulfone composition comprising:
- an aromatic polysulfone;
- and
- an organic compound having a boiling point no lower than 100° C. and no higher than 400° C.;
- wherein
- the organic compound is contained in an amount of at least 0.1 ppm and at most 12 ppm relative to the mass of the aromatic polysulfone;
- and
- the aromatic polysulfone has repeating units expressed by formula (1):
- -Ph1-SO2-Ph2-O— (1)
- where, in formula (1), Ph1 and Ph2 represent phenylene groups, in which one or more hydrogen atoms that bind to the phenylene groups may, independently of each other, be substituted with an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 20 carbon atoms, or a halogen atom.
A molded article comprising:
- an aromatic polysulfone;
- and
