The invention provides a polymer used for flame retardant materials, which is a polymer formed by the polymerization of phosphorus-based monomers, a polymer formed by the polymerization of nitrogen-based monomers, or a polymer formed by the copolymerization of phosphorus-based monomers and nitrogen-based monomers. The polymer formed; wherein the structure of the phosphorus-based monomer is as follows: R is hydrogen, phenyl, C 1-12 alkylphenyl, C 1-12 alkyl, C 1-12 ether, C 1-12 alkanol, or C 1-12 hydroxyalkane R 2 is a phenylene group, a C 1-12 alkylphenylene group, a C 1-12 alkylene group, a C 1-12 ether alkylene group, a C 1-12 alkylol alkylene group, or a C 1 The hydroxyalkylene group of -12 ; wherein the structure of the nitrogen monomer is as follows: R 3 is hydrogen, phenyl, C 1-12 alkylphenyl, C 1-12 alkyl, C 1-12 ether, C 1-12 alkanol, or C 1-12 hydroxyalkane R 4 is a phenylene group, a C 1-12 alkylphenylene group, a C 1-12 alkylene group, a C 1-12 ether alkylene group, a C 1-12 alkylol alkylene group, or a C 1 -12 Hydroxyalkylene. The invention also provides a polymer blend used for flame retardant materials. The invention also provides a flame retardant material comprising the polymer or polymer blend. |
