Abstract
This disclosure provides fire retardant materials, including polymers that include at least one pyridinium salt moiety and at least one phosphine oxide moiety. In some cases, fire retardant polymers provided herein have the following structure:
Claims11
A fire retardant polymer comprising at least one pyridinium salt moiety and at least one phosphine oxide moiety, wherein the polymer has the following structure:
- wherein R1 and R6 are each N;
- wherein R2 and R7 are each negatively charged counterions;
- wherein R3, R4, R8, R9, R11, R13, R14, R15, and R16 are each selected from the group consisting of H and groups comprising one or more carbon atoms;
- and
- wherein R5, R10, and R12 are any group comprising one or more carbon atoms, and
- wherein n is a number between 2 and about 100,000.
A method of making a polymer comprising at least one pyridinium salt moiety and at least one phosphine oxide moiety, the method comprising reacting a bispyrylium compound with a diamine phosphorous oxide using a ring-transmutation polymerization reaction.
