ABSTRACT:
A thermoplastic resin contains a polymer, and the polymer includes a divalent phosphate residue having a spiro ring, represented by formula (1), in a molecule and has a number average molecular weight of at least 2,000:wherein R1is independently selected from the group consisting of a hydrogen atom, a halogen atom, an aliphatic hydrocarbon group having the carbon number of 1 to 20, an aromatic hydrocarbon group having the carbon number of 1 to 20, and a nitro group; p and q are integers satisfying p+q=0 to 16; X independently represents oxygen, sulfur, selenium, or an unshared electron pair; Y is independently selected from oxygen, sulfur, and a methylene group; and n and m are integers satisfying n+m=0 to 4.
