Abstract:

A key part of the development of new polymeric materials focuses on the use of flame-retardant additives, which help to reduce the inherent flammability of polymers and the production of smoke and toxic gases. The aim of this thesis was the preparation, characterization and application of new polymeric flame-retardant additives, which can lead to intumescent systems when mixed with ¨commodity¨ polymers. The synthesis of this kind of additives was carried out by chemical modification of different polymeric structures (alcohols, polyketones, polyaziridines) with phosphorous moieties, previously

Due to their outstanding properties, poly(arylene ethers) are useful as toughness modifiers in epoxy resins (EP). Furthermore, these polymers show rather low intrinsic fire risks. According to recent research it has been incorporated that poly(arylene ether phosphine oxides) [PAEPO’s] can further improve the fire behavior. Increasing phosphorous content of the PAEPO can influence the fire behavior too. Fire retardants containing phosphorus – regardless of whether an additive or reactive approach is used – show different mechanisms in the condensed and gas phase. In the present study PSU Contro

Abstract:

Antimony trioxide (Sb2O3) is a common additive in flame retardant formulations and a study has been made to determine the effects of adding it alone, or with four commercial brominated materials (OBDPO, BTBPE, TBBA and PDBS80) to ABS polymer. The results focus upon mechanical, rheological, microscopical and flame retardant properties, and the effects of different Sb2O3 grades with average particle sizes ranging from 0.1 to 11.8 μm. The Sb2O3 was mainly studied up to 12 wt% loading in ABS, since this is considered to be the maximum level used in commercial flame retardant formulations.

Much of the work centred around the chemistry of a key starting material, pentaerythritol phosphate (PEPA).

Polymers are widely used across the globe in applications ranging from construction to biomedical, with increasing usage as time progresses. However, despite their prevalence polymers can be highly flammable materials, and though this may be combatted with the use of flame retardant additives, the additives themselves may have a detrimental effect on other properties of a polymeric material such as its aesthetics or structural integrity.

Abstract:

Antimony trioxide (Sb203) and halogenated additives are used together in flameretarded formulations due to their synergistic retardant properties. A study has been made to determine the effects of adding different grades of Sb203 (dSD particle sizes 0.11 um, 0.52um and 1.31 um) into ABS polymer either alone or with commercial brominated materials (BTBPE, TBBA, DBDPO) and an experimental bromine grade (sDBDPO). The Sb20 3 was added at 4wt% loadings and the bromines at 20wt% loadings. The results consider the influence of the additives on processing, mechanical, morphological and flame retardant

Abstract:

[P=O]-containing compounds and luminescent Ln(III) and Mn(II) complexes were prepared for applications in polymeric materials as flame retardants and markers. The experimental work first concerned the investigation of a new synthetic route to functionalize DOPO (6H-dibenzo[c,e][1,2]oxaphosphinine 6-oxide) by formally replacing the P-bonded hydrogen atom with N- and O-containing fragments. The second part concerned the synthesis of new luminescent Ln(III) and Mn(II) complexes and the investigation of their optical properties. The [P=O]-containing compounds and the complexes were characterized b

Abstract:

Ce mémoire porte sur l’étude de l’ignifugation d’une résine époxyde grâce à l’utilisation de nanoparticules. L’incorporation de Polyhedral Oligomeric Silsesquioxanes (POSS) ou de nanotubes de carbone seuls dans la matrice apporte une amélioration très limitée des propriétés feu. La fonctionnalisation covalente de nanotubes de carbone par des fonctions retardatrices de flamme a été réalisée et caractérisée, mais elle n’augmente pas les performances feu de la matrice chargée en nanotubes de carbone. La combinaison entre un retardateur de flamme phosphoré (APP) et les nanotubes de carbone révèle
