Synthesis of three novel intumescent flame retardants having azomethine linkages and their applications in EVA copolymer
Three novel intumescent flame retardants (IFRs), polyphosphate esters (designated as PDP, PEP, and PPP), were synthesized by reacting phenyl dichlorophosphate with three bis-hydroxy azomethine monomers through interfacial polycondensation. The polyphosphate esters were characterized by hydrogen nuclear magnetic resonance (1H-NMR), fourier transform infrared spectroscopy (FTIR), and gel permeation ...

An investigation into synergistic effects of rare earth oxides on intumescent flame retardancy of polypropylene/poly (octylene-co-ethylene) blends
Synergistic effects of two kinds of rare earth oxides (REOs), neodymium oxide (Nd2O3) or lanthanum oxide (La2O3) on the intumescent flame retardancy of thermoplastic polyolefin (TPO) made by polypropylene/poly (octyleneco-
ethylene) blends were investigated systemically by various methods.

A novel zinc chelate complex containing both phosphorus and nitrogen for improving the flame retardancy of low density polyethylene
A novel metal chelate complex, Zn-TEPAPM, was synthesized through reacting Zn(OAc)2 with the ligand of tetraethyl (1,2-phenylenebis(azanediyl)) bis (2-hydroxylphenylmethylene) diphosphonate (TEPAPM) and characterized by FT-IR, 1H-NMR, and 31P NMR spectra. The flame retardancy and thermal behavior of the intumescent flame retardant low density polyethylene (LDPE) containing Zn-TEPAPM were investiga...

Thermal degradation and flame retardancy properties of ABS/lignin: Effects of lignin content and reactive compatibilization
Effects of alkali lignin incorporation and in situ reactive compatibilization on the thermal stability and flame retardancy of ABS were investigated. Morphology observations show that lignin can form submicron dispersed phases in ABS matrix regardless of compatibilization. Thermal analyses show that lignin will cause a slight thermal instability of ABS due to its relatively lower thermal stability...

Preparation of Layered Double Hydroxide Wrapped Carbon Nanotubes and its application as a flame retardant for polypropylene
Carbon nanotubes wrapped with layered double hydroxide (LDH-w-CNTs) was facilely obtained through in-situ introducing CNTs into the hydrothermal reaction system of LDH, with the goal of combining their unique physical and chemical characteristics to meet new advanced applications. Morphology observation indicated that LDH lamella enwrapped on the surface of CNTs and the wrapping degree was depende...

Effect of styrene-maleic anhydride as a compatibilizer on the mechanical properties and flammability of intumescent flame retardant polystyrene
Polystyrene (PS) was flame-retarded with a polymeric intumescent flame retardant, poly (diaminodiphenyl methane spirocyclic pentaerythritol bisphosphonate) (PDSPB), and in situ compatibilized with styrene-maleic anhydride copolymer (SMA). Compatibilization reaction was verified by IR spectroscopy and gel content measurement. Electron microscopy images showed that compatibilization could considerab...

The effects of irradiation cross-linking on the thermal degradation and flame retardant properties of the HDPE/EVA/magnesium hydroxide composites
High-density polyethylene (HDPE)/ ethylene vinyl-acetate copolymer (EVA)/magnesium hydroxide （Mg(OH)2） composites were cross-linked by high-energy electron beam irradiation in the presence of triallylisocyanurate (TAIC). The effects of high-energy electron beam irradiation on the properties of the HDPE/EVA/Mg(OH)2 composites were investigated by the Advanced Rheology Expansion System (ARES©...
