“…The tensile and flexural strength of the cured EP/18 wt % BDMPP composites are as high as 83.4 MPa and 125.8 MPa, respectively. In previously reported works, [27][28][29][30] the triphenyl phosphine(Ph 3 P) was used as a curing accelerator during the curing procedure of EP. In this work, the chemical structure of the synthesized BDMPP was similar with Ph 3 P. As a result, this phenomenon may be attributed to that the incorporation of BDMPP flame retardant additive stimulate the formation of the intercrosslinking network of EP thermosets and then increase the molecular rotational barrier of EP, consequently enhance the mechanical properties of the EP/BDMPP composite thermosets.…”

A novel phosphonate flame retardant additive bis(2,6-dimethyphenyl) phenylphosphonate (BDMPP) was synthesized from phenylphosphonic dichloride and 2,6-dimethyl phenol, and its chemical structure was characterized by Fourier transform infrared (FTIR) spectroscopy, 1 H and 31 P nuclear magnetic resonance. The prepared BDMPP and curing agent m-phenylenediamine were blended into epoxy resins (EP) to prepare flame retardant EP thermosets. The effect of BDMPP on fire retardancy and thermal degradation behavior of EP/BDMPP thermosets was investigated by limiting oxygen index (LOI), vertical burning test (UL-94), cone calorimeter and thermalgravimetric analysis (TGA). The morphologies of char residues of the EP thermosets were investigated by scanning electron microscopy (SEM) and the water resistant properties of thermosets were evaluated by putting the samples into distilled water at 708C for 168 h. The results demonstrated that the cured EP/14 wt % BDMPP composites with the phosphorus content of 1.11 wt % successfully passed UL-94 V-0 flammability rating and the LOI value was as high as 33.8%. The TGA results indicated that the introduction of BDMPP promoted EP matrix decomposed ahead of time compared with that of pure EP and led to a higher char yield at high temperature. The incorporation of BDMPP enhanced the mechanical properties and reduced the moisture absorption of EP thermosets. The morphological structures of char residue revealed that BDMPP benefited to the formation of a more compact and homogeneous char layer on the materials surface during burning, which prevented the heat transmission and diffusion, limit the production of combustible gases and then lead to the reduction of the heat release rate. After water resistance tests, EP/ BDMPP thermosets still remained excellent flame retardancy.

The inclusion of organometallic units into polymeric structures has attracted much attention in different fields according to the nature and behaviour of the inserted metal. Moreover, the discovery of organometallic polymers and their structural characterization initiated an explosive rebirth of organometallic chemistry. Organometallic moieties are in or pendent to the polymer backbone and examine some of the uses of the emergent metallocene polymers, and new uses are still being found for these remarkable organometallic moieties. This review gives a simple introduction to variable organometallic molecules and their characteristics. This review will focus on the syntheses and characterization of organometallic polymers, including ferrocene-and phosphorus-containing polymers. A general overview on ferrocene polymers with a special attention to ferrocene-containing liquid crystalline polymers (including a ferrocene moiety in the main chain, side-chain or dendrimers) and fullerene-ferrocene liquid crystalline polymers is presented. In addition, more details for synthesis and properties of phosphorus-containing polymers are illustrated.

The flame-retardant efficacy of phosphorus-containing reactive amine hardeners for epoxy resins is well-known; however their synthesis often applies hazardous, objectionable reagents. The aim of this work is to develop an effective synthesis method for the preparation of P-containing amines, which can act as flame-retardant crosslinking agent in epoxy resins. The syntheses and testing of an aliphatic and two aromatic amines are described: curing properties, glass transition temperature, thermal stability, and flameretardant performance of the amines are studied. On the basis of these results, the scaling-up and the optimization of the synthesis of the phosphorus-containing aliphatic amine hardener in ReactIR TM in situ FTIR apparatus is discussed.
