摘要: A novel flame retardant additive, DOPO-based polymeric phosphate (PFR-D), which simultaneously contained phosphorus and sulfur, was synthesized from 9,10-dihyro-9-oxa-10-phosphaphnanthrene-10-oxide (DOPO), POCl3 bisphenol S. And the structure of PFR-D has been characterized by 1H-NMR, 31P-NMR FT-IR. used as additive in polycarbonate/acrylonitrile-butadiene-styrene alloy (PC/ABS). The UL94 V-0 rating achieved addition 5-7% PC/ABS, LOI reached 27.5%. thermal degradation polymers with it investigated TGA, results showed that apparently changed pyrolysis pathways PC/ABS. TGA curves indicated effect attributed to promoting char yield involving polymer charring.
