titleOfInvention | Phosphorus-containing resin and method for producing the same |
abstract | (57) [Summary] (with correction) [PROBLEMS] To provide a resin having a high refractive index, a low dispersibility, and a good color tone while being a thermoplastic resin. SOLUTION: It contains a phosphonic acid residue represented by the following general formula (1) and a dihydric phenol residue and a carbonate residue represented by the following general formula (2), and comprises a phosphonic acid residue and a carbonate residue. General formula (1) in which the mole fraction satisfies formula (3) General formula (2) [In the formula (1), R represents a hydrocarbon group having 1 to 20 carbon atoms, and X represents oxygen, sulfur, or selenium. In the formula (2), R ′ is each independently a hydrogen atom, an aliphatic hydrocarbon group having 1 to 20 carbon atoms, An aromatic hydrocarbon group having 1 to 20 carbon atoms, a halogen atom, selected from the group consisting of a nitro group, Y is a single bond, an oxygen atom, It is selected from the group consisting of a sulfur atom, an alkylene group, an alkylidene group and the like. 1> (a) / [(a) + (b)] ≧ 0.05 (3) [where, (a) indicates the number of moles of a phosphonic acid residue and (b) indicates the number of moles of a carbonate residue. Is dissolved in an organic solvent, the solution is added to another solvent maintained at a temperature equal to or higher than the boiling point of the organic solvent, and the resin is purified by a step of isolating the resin. |
