“…In our previous study, a phosphorous-and nitrogencontaining monomer was incorporated into PS backbone via radical copolymerization. 23 Similarly, it was found that the thermal stability of the copolymer evaluated in air condition, was higher than that in nitrogen. However, Wang and coworkers prepared a phosphorus-containing polymer with a similar structure.…”

A phosphorus-and nitrogen-containing compound (2-dimethylamino ethyl phenyl hydroxyethyl acrylate phosphate) and its oligomer (poly(2-dimethylamino ethyl phenyl hydroxyethyl acrylate phosphate), PDPHP) were synthesized and characterized. The polystyrene (PS) composites with various amounts of PDPHP were prepared by melt blending. The thermal stability of the PDPHP and PS composites was investigated by thermogravimetric analysis. The flame retardancy of the composites was evaluated using microscale combustion calorimeter and limiting oxygen index test. A Fourier transform infrared (FTIR) spectroscopy coupled with a thermogravimetric analyzer was also used to study the gas phase from the degradation of PS composites. The char residues of the PS composites containing 30 wt % PDPHP were analyzed by FTIR and scanning electron microscopy. The results suggest that the incorporation of PDPHP into PS can evidently enhance the char formation and improve the flame retardancy of virgin PS. The compact and coherent char formed during degradation was attributed to the enhancement of char quality and flame retardance.

“…Reactive method, that is, flame‐retardant moiety is introduced into PS backbone via radical copolymerization. This method has less adverse effects on mechanical properties than the “additive” approach . In order to improve the thermal stability and compatibility of P‐N flame retardants, covalent bonding can be employed to make the compounds into macromolecular structure …”

“…The combustion flow calorimetry results reflected that the peak heat release rate (pHRR) had a certain degree decrease with the increasing comonomer incorporation into the copolymer. Tai et al synthesized a monomer, acryloxyethyl phenoxy phosphorodiethyl amidate (AEPPA), and prepared various amounts of styrene (St) copolymers by free radical bulk polymerization between AEPPA and St . AEPPA can decrease pHRR, indicating that AEPPA has a flame‐retardant effect to a certain extent.…”

In order to improve the flame retardancy of polystyrene (PS), a phosphorus and nitrogen comonomer, named AC2NP2, was synthesized and then incorporated into various amounts of PS by seeded emulsion polymerization. The modified methacrylate (AC2NP2) was used as the core phase, the styrene as the shell phase, then flame‐retardant effect copolymers with core‐shell structure were prepared successfully. The particle size was ranged from 40 to 60 nm, and the structure and properties of the copolymers were characterized in detail. Notably, despite a few amounts of the AC2NP2 units in the copolymers, all the copolymers exhibited significantly enhanced thermal stability and reduced flammability as compared with pure PS. Furthermore, from differential scanning calorimetry test, it was observed that the glass transition temperature was tinily influenced with the incorporation of commoner. The incorporation of P‐N comonomer into PS backbone did not lead to negative effect on the glass transition behavior of PS.

“…[6,7] As far as we known, the excellent flame retardants usually contain some essential elements, such as halogen, phosphorus, nitrogen, boron, silicon, etc. [8][9][10][11][12][13] Due to the enhanced requirement for environment concerns, the halogen-free flame retardants have been widely used to inhibit the flammability of PS, especially phosphorus-containing flame retardants. [14,15] Up to now, two main flame retardant mechanisms was proposed for the phosphorus-containing flame retardants.…”
