Abstract

The invention relates to polylactide-based polymer or copolymer (PLA) compositions withimproved flame retardancy properties as obtained by conventional melt-blending ofPLA polyester matrix (1) with both calcium sulfate (2) and organo-modified layered silicates (OMLS) (3). Combination of CaSO 4 and OMLS exhibits synergistic effects on PLA flame retardancy by both significantly increasing the time to ignition and decreasing the heat release rateper unit area, and promoting non-dripping properties. Moreover,all other properties of PLA remain almost unchanged or are improved as regards to pristine PLA, especially thermal and mechanical properties.
