摘要: Summary: It is a big challenge to improve simultaneously both the flame retardancy and melt-dripping resistance of polymeric materials such as PET. In this paper, novel intumescent retardant, DPSPB, was synthesized blended with copolyester PET-co-DDP/O-MMT nanocomposites, which were by polycondensation TPA, EG, DDP, O-MMT. The resulting PET-co-DDP/O-MMT/DPSPB nanocomposites exhibit very good retardance dripping resistance, e.g., LOI = 29, UL-94 V-0. SEM, XRD, XPS used investigate relationships between structures properties composites. proved that DPSPB offers excellent protection for structure responsible anti-dripping nanocomposites. Residues copolyesters after combustion: common nanocomposite residue PDMN (left) PDMN/DPSPB (right).
