A flame retardant synergist including a repeating unit including a backbone represented by a formula of:

##STR00001##

where moiety A is derived from a substituted triazine having at least two amino groups, and where moiety B is derived from a dialdehyde having a terminal aldehyde. Furthermore, moiety A and moiety B are bonded via a CN linkage formed from having one of the at least two amino groups reacted with the terminal aldehyde, where n ranges from 5 to 1000. Additionally, one or more side units extend from the backbone, where the one or more side units are derived from 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide or a derivative thereof. Furthermore, a flame retardant polymer composite that includes a polymer, the flame retardant synergist, and a flame retardant additive, is disclosed herein. Methods of forming the flame retardant synergist and the flame retardant polymer composite are further disclosed herein.

Main chain polyamines comprise amine and ammonium groups along the polymer backbone. Main chain polyamines can be used as pharmaceutical agents and in pharmaceutical compositions. The main chain polyamines are particularly useful in the treatment or prevention of mucositis and infection, specifically oral mucositis and surgical site infection.
