Synthesis of a novel aluminium salt of nitrogen-containing alkylphosphinate with high char formation to flame retard acrylonitrile-butadiene-styrene.

ABSTRACT: A novel nitrogen-containing alkylphosphinate salt-aluminium β-(p-nitrobenzamide) ethyl methyl phosphinate (AlNP) was synthesized and used to flame retard acrylonitrile-butadiene-styrene copolymer (ABS). The Fourier transform infrared spectrometry, ¹H, ¹³C and ³¹P nuclear magnetic resonance and X-ray fluorescent spectroscopy (XRF) were applied to characterize the structure and composition of products. The flame retardancy performance, thermal properties and mechanical strength of the ABS/AlNP with respect to AlNP loading were investigated. AlNP was stable before 330°C and decomposed very slowly with residues high up to 56.1% at 700°C. Adding 25-30 wt% of AlNP alone can make ABS to pass V0 rating in the vertical burning tests (UL 94). The results according to
