This study investigates the effects of weak intermol. interactions on the flame retardancy of a poly(ethylene terephthalate) (PET) and polyphosphazene flame retardant. Monodispersed poly-(cyclotriphosphazene-co-4,4′-sulfonyldiphenol) (PZS) microspheres with different diameters were synthesized by controlling the reactant concentration Simulation studies revealed that the weak intermol. interactions between PZS and PET predominantly include strong hydrogen bonding and π-π interactions. The weak intermol. interactions imparted high thermal stability, even in the molten state, and PZS microspheres with smaller diameters achieved stronger hydrogen bonds and π-π interactions with PET. The diameter of the PZS microspheres influenced the limiting oxygen index value and UL-94 rating. Increasing the carbon residue alone was insufficient to promote the flame retardancy, and the weak intermol. interactions played an important role. Thus, stronger weak-intermol.-interactions are beneficial for realizing a material with superior flame retardancy and anti-dropping performance.
