Abstract: A flame retardant synergist including a repeating unit including a backbone represented by a formula of: 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 —C—N— 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.

Abstract: A polymer having a backbone and a side unit of 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide bonded thereto, where the backbone of the polymer includes at least one heterocyclic moiety. There is also provided a process for producing the polymer as defined herein as well as a flame retardant polyolefin formulation including the polymer as defined herein and a moulded article including the flame retardant polyolefin formulation as defined herein.
