A polymer composition includes a polymer and a flamenretardant. The flame retardant includes: at least onennucleic-acid-related substance that is selected from thengroup consisting of a nucleic acid base, a nucleoside, annucleotide and a polynucleotide; and/or at least onenderivative of the nucleic-acid-related substance. Thenderivative is selected from the group consisting of: (a) ansulfate, a nitrate, a borate, a hydrochloride or annisocyanurate of the nucleic acid base; (b) a metal salt of thennucleotide; and (c) a compound obtained by substituting annalkyl group having 1 to 4 carbon atoms, an aryl group having 6nto 10 carbon atoms, an alkoxy group or a mercapto group for anhydrogen atom that is bonded to a nitrogen atom of the nucleicnacid base, the nucleoside or the nucleotide. |
