Patent ID: 6987139

Claim:
A polymer composition comprising a polymer and a flame retardant, wherein the flame retardant includes: at least one nucleic-acid-related substance that is selected from the group consisting of a nucleic acid base, a nucleoside, a nucleotide and a polynucleotide; and/or at least one derivative of the nucleic-acid-related substance, the derivative being selected from the group consisting of: (a) a sulfate, a nitrate, a borate, a hydrochloride or an isocyanurate of the nucleic acid base; (b) a metal salt of the nucleotide; and (c) a compound obtained by substituting an alkyl group having 1 to 4 carbon atoms, an aryl group having 6 to 10 carbon atoms, an alkoxy group or a mercapto group for a hydrogen atom that is bonded to a nitrogen atom of the nucleic acid base, the nucleoside or the nucleotide; wherein the at least one nucleic-acid-related substance is at least one monomer that is selected from the group consisting of the nucleic acid base, the nucleoside and the nucleotide, the at least one monomer being polymerized with another polymerizable component.
