Patent ID: 8722823

Claim:
A polymer, polymerized of a nitrogen-based monomer, a phosphorous-based monomer, or combinations thereof, wherein the phosphorous-based monomer has the formula: wherein R 1 consists of hydrogen, a phenyl group, a C 7-12 alkyl phenyl group, a C 1-12 alkyl group, a C 2-12 ether group, a C 1-12 alkoxyl group, or a C 1-12 hydroxylalkyl group, and R 2 consists of a phenylene group, a C 7-12 alkyl phenylene group, a C 1-12 alkylene group, a C 2-12 ether group, a C 1-12 alkylene glycol group, or a C 1-12 hydroxylalkylene group, and wherein the nitrogen-based monomer has the formula: wherein R 3 consists of hydrogen, a phenyl group, a C 7-12 alkyl phenyl group, a C 1-12 alkyl group, a C 2-12 ether group, a C 1-12 alkoxyl group, or a C 1-12 hydroxylalkyl group, and R 4 consists of a phenylene group, a C 7-12 alkyl phenylene group, a C 1-12 alkylene group, a C 2-12 ether group, a C 1-12 alkylene glycol group, or a C 1-12 hydroxylalkylene group, wherein the polymer has a weight-average molecular weight of about 1,000 to 1,000,000.
