<p>Technologies are generally described for a system and method effective to prepare a flame retardant. In one example, a method may include copolymerizing a mixture of monomers. The mixture of monomers may include at least one dicarboxylic acid monomer, at least one diamine monomer, and at least one monomer having the formula (I) wherein Rl is hydroxyl, halogen, alkoxy, or aryloxy; wherein R2 is hydroxyl, halogen, alkoxy, or aryloxy; wherein R3 is H or -L-R5; wherein R4 is H or L-R5; wherein if R3 is H, then R4 is L-R5; wherein L is alkyl, cycloalkyl, aryl, heteroaryl, or -(R6-O-R7)n-; wherein R6 is alkyl, cycloalkyl, aryl, or heteroaryl, wherein R7 is alkyl, cycloalkyl, aryl, or heteroaryl, wherein n is an integer from 1 to 12; wherein R5 is a flame retarding moiety comprising P, N, halogen, or B; and wherein q is an integer from 1 to 12.</p> |
