A series of aromatic hyperbranched polyethers have been synthesized from cyanuric chloride and diols by using nucleophilic displacement polymerization technique. The synthesized sulfur containing polyether was blended with commercially available low density polyethylene (LDPE) and plasticized poly(vinyl chloride) separately to improve the flame retardant property of those linear polymers. The flame retardancy of blends at different dose levels of the hyperbranched polyether with those linear polymers was investigated by measurement of limiting oxygen index (LOI) value and thermogravimetric analysis. The LOI values and TG analysis of these blends indicated that the hyperbranched polyether act as flame retardant additive.

The polyamidoamine derived from N,N′-methylenebisacrylamide (M) and glycine (G), M-G, has been shown to be an effective flame-retardant (FR) for cotton in horizontal flame spread tests (HFST), extinguishing the flame at 5% add-on. Its activity was attributed to its intrinsic intumescence. In vertical flame spread tests (VFST), M-G failed to extinguish the flame even at 30% add-on. Conversely, in VFST, the polyamidoamine derived from M and cystine (C), M-C, inhibited cotton combustion at 16% add-on, but in HFST failed to extinguish the flame below 12% add-on. Its activity was ascribed to the release of sulfur-containing volatiles acting as radical scavengers. In this work, the FR effectiveness of M–Gm–Cn copolymers with different G/C ratio was compared with that of the M–G and M–C homopolymers and of M–G/M–C blends of the same compositions. In HFST, both copolymers and blends extinguished the flame. In particular, M–G50–C50 and (M–G/M–C)50/50 extinguished the flame, even at 7% add-on. In VFST, the copolymers with ≥50% M–C units, similar to M–C, inhibited cotton combustion at 16% add-on. At the same add-on, the M–G/M–C blends failed to extinguish the flame. It may be concluded that, in contrast to blends, copolymers combined the merits of both homopolymers in all tests.
