Flame retardant nylon

A flame retarding polymer reaction product of at least one monomer, wherein the monomer has the formula (I),

• wherein R1 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.

A method of preparing a flame retarding polymer, the method comprising copolymerizing a mixture of monomers;

• 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.
