Abstract
Brominated flame-retardants are one of the common and efficient compounds in producing flame retardant plastics and antimony trioxide is often used as a synergistic agent for halogenated flame-retardants. In this research, a new reactive flame retardant, maleated tetrabromobiphenol-A (MTBBA) crystals, has been introduced for the first time and its structure was fully characterized by high-field 1H NMR and 13C NMR spectroscopy. The improvement in flame-retardancy effect of styrene–maleic anhydride copolymer by MTBBA and also their compounded samples with Sb2O3 was investigated as the main purpose in this work. Limiting oxygen indexes (LOI) for the neat terpolymers and the compounded samples were measured by flammability tests. Also thermal gravimetry analysis (TGA) and differential scanning calorimetry (DSC) were applied in order to study thermal behavior of the samples. The results of thermal analysis were used to observe the effect of insertion of this novel monomer into the copolymer chain in comparison with styrene–maleic anhydride copolymer.
