| titleOfInvention | Polycarbonate and Polycarbonate Manufacturing Method |
| abstract | A polycarbonate production method comprising the following step (a) and step (b): (a) a reaction step of at least one type of fluorine-containing carbonate selected from the group consisting of a compound represented by the Formula (1), a compound represented by Formula (2), a compound represented by Formula (3) and a compound represented by Formula (4), and an aromatic dihydroxy compound in the presence of a condensation catalyst, to obtain a prepolymer; and (b) a step of heating the prepolymer to a temperature that is lower than the melting temperature of the prepolymer and conducting a solid phase polymerization in the prepolymer while discharging a fluorine-containing alcohol, which is produced as by-product, to obtain a polycarbonate: [Chemical formula 1] ** (See formula) ** in which, R1 represents a group represented by CA1B1R4 and two R1 can be the same or different from each other, R2 represents a group represented by CA2B2R5 and two R2 can be the same or different from each other, R3 represents a hydrogen atom or a group represented by CA3B3R6 and two R3 can be the same or different from each other, A1 to A3 each represent a hydrogen atom, a fluorine atom or Rf , B1 to B3 each represent a hydrogen atom, a fluorine atom or Rf, R4 to R6 represent a fluorine atom, Rf or ORf, and Rf represents a fluoroalkyl group (which may contain an ethereal oxygen) having 1 to 12 to carbon atoms or a fluoroaryl group (which can contain an ethereal oxygen) having 6 to 10 carbon atoms; [Chemical formula 2] ** (See formula) ** in which, R1 represents a group represented by CA1B1R4, R2 represents a group represented by CA2B2R5, R3 represents a hydrogen atom or a group represented by CA3B3R6, R7 represents an atom hydrogen, R8 represents a perfluoroalkylene group (which can contain an ethereal oxygen) having 1 to 5 carbon atoms, A1 to A3 each represent a hydrogen atom, a fluorine atom or Rf, B1 to B3 each represent a hydrogen atom, a fluorine atom or Rf, R4 to R6 represent a fluorine atom, Rf or ORf, and Rf represents a fluoroalkyl group (which may contain an ethereal oxygen) having 1 to 12 carbon atoms or a fluoroaryl group (which may contain ethereal oxygen) having 6 to 10 carbon atoms; [Chemical formula 3] ** (See formula) ** in which, R7 represents a hydrogen atom and R8 represents a perfluoroalkylene group (which can contain an ethereal oxygen) that has 1 to 5 carbon atoms and two R8 can be the same or different from each other; and [Chemical formula 4] ** (See formula) ** in which, R9 to R13 each represent a hydrogen atom, a fluorine atom, or a fluoroalkyl group (which may contain an ethereal oxygen) having 1 to 6 carbon atoms, two R9, two R10, two R11, two R12 and two R13 can be respectively the same or different from each other, and the molecule includes at least one fluorine atom |
