A new approach for the simultaneous improvement of fire retardancy, tensile strength and melt dripping of poly(ethylene terephthalate)

A kind of synthesized thermotropic liquid crystal copolyester containing phosphorus (PLCP) with high flame retardancy (oxygen index, 70%) has been used to prepare in situ reinforced PET composites that have both good flame retardancy and better mechanical properties than pure PET. The melt dripping behavior of PET was also improved.
