“…It has also been reported that polycondensates are produced from the rearrangements of phenol formaldehyde resins in their main thermal degradation and so that the flame retardancy is enhanced [7][8][9] . As well, due to the interaction between TPP and phenol resins, the evaporation temperature of TPP is elevated further [6,[10][11][12] and it could also contribute to the flame retardancy of the polymer.…”

Thermal and thermo-oxidative decomposition and decomposition kinetics of flame retardant high impact polystyrene (HIPS) with triphenyl phosphate (TPP) and novolac type epoxy resin (NE) were characterized using thermo-gravimetric experiment. And the flammability was determined by limited oxygen indices (LOI). The LOI results show that TPP and NE had a good synthetic effect on the flame retardancy of HIPS. Compared with pure HIPS, the LOI values of HIPS/NE and HIPS/TPP only increased by about 5%, and the LOI value of HIPS/TPP/NE reached 42.3%, nearly 23% above that of HIPS. All materials showed one main decomposition step, as radical HIPS scission predominated during anaerobic decomposition. TPP increased the activity energy effectively while NE affected the thermal-oxidative degradation more with the help of the char formation. With both TPP and NE, the materials could have a comparable good result of both thermal and thermal-oxidative degradation, which could contribute to their effect on the flame retardancy.

“…HIPS composed of PS main chain and grafted-polybutadiene rubber is commonly blended with PPE due to their good miscibility, resulting in enhanced impact strength. 10,17,18 Thus, HIPS is incorporated into the nylon 66/PPE blends as an impact modifier. Figure 2 shows the variation in the mechanical properties of PPE/HIPS binary blends with their composition.…”

The optimum weight ratio of each component in the compatibilized blends of nylon 66/poly(2,6-dimethyl-1,4-phenylene ether)/high-impact polystyrene with polystyrene-co-maleic anhydride and styrene-ethylene-butylene-styrene block copolymer grafted with maleic anhydride was determined in terms of exhibiting balanced mechanical properties. The mechanical strength of the blends was deteriorated with increasing phosphinate-based flame retardant content while the tensile modulus increased. For UL94V test, the addition of ;10 wt% phosphinate did not have a significant effect on the flame retardancy showing V2 grade while further addition gave rise to char formation resulting in V0 grade. Limiting oxygen index values increased greatly by ca. 34% at Downloaded from 5 wt% phosphinate, followed by mild increase by further addition. Heat release rate peaks of the blends were reduced and broadened with increasing phosphinate content showing little difference from 15 wt%. The complex viscosity increased with phosphinate content, but its increasing extent decreased at a high frequency. In the Cole-Cole plot, the presence of the phosphinate shifted the plot from unfilled blends without showing a single master curve depending on its loading level.

“…Flexible flame‐retardant materials are desirable for use in wire coatings for flexible wire insulation, USB cables, cell‐phone chargers/adapters, and internal wiring. Poly(2,6‐dimethyl‐l,4‐phenylene ether) (PPE) is an excellent flame‐retardant material due to its high limiting oxygen index, halogen‐free, compliant with environmental regulations, high heat distortion temperature, and low specific gravity; however, it is brittle and unprocessable. Due to its unprocessability, modified PPE, a blend of PPE and PS, is usually used for industrial products, but the flame retardancy of modified PPE is insufficient without including flame retardant additive .…”

We observed that modified polyphenylene ether (PPE) was solubilized in thermoplastic styrenic elastomer (TPS) and that a two-phase lacy structure formed on nanometer scales when the TPS composition was 67 wt % and modified PPE and polystyreneblock-poly(styrene-co-ethylene-co-butylene)-block-polystyrene (S-SEB-S triblock copolymer) were blended. However, the molecular weight of the outer PS block segments M outPS and the content of the outer PS block segments / outPS were <10,000 g/mol and 20 wt %, respectively. The resulting S-SEB-S/modified PPE nano-alloy exhibited both flexibility and flame retardancy, unlike other materials, where a trade-off exists between these two properties; that is, the flame retardancy was excellent when the phosphorus additive was present. This combination of properties might be attributed to the two-phase nanometer-scale structure consisting of flame-retardant styrene/PPE domains and a continuous soft, lacy SEB matrix. The results for polystyrene-block-poly(ethylene-co-butylene)-block-polystyrene (S-EB-S triblock copolymer)/modified PPE blends were presented for comparison. V C 2014 Wiley Periodicals, Inc. J. Appl.
