    摘要: A significant disadvantage of the use of polylactic acid (PLA), lack of flame retardance, has been overcome by the use of polyphosphonate-co-carbonate in combination with an impact modifier, a drip suppressant, and optionally, an epoxy functional styrene-acrylate oligomeric chain extender. The compound achieves a UL 94 rating of V-0 or V-1 and a Notched Izod value of more than about 5 ft-lbs/in. The compound also exceeds a threshold of 100° C. in heat deflection temperature.

    摘要: A significant disadvantage of the use of polylactic acid (PLA) has been overcome by the use of styrene maleic anhydride copolymer (SMAC) to cause an unexpected increase in the heat deflection temperature of the PLA compound, surpassing a delta improvement of 5° C. over the heat deflection temperature of the PLA alone, at 66 psi as measured using ASTM D648 when the blended compound is essentially dried prior to use. The compound also often exceeds a threshold of 65° C. in heat deflection temperature. Use of a compatibilizer and impact modifier further improves the industrial versatility of the heat resistant PLA compound. Alternatively, use of calcium carbonate in the heat resistant PLA compound also is industrially valuable.

    摘要: A significant disadvantage of the use of polylactic acid (PLA) has been overcome by the use of acrylonitrile-butadiene-styrene (ABS) in combination with an epoxy functional styrene-acrylate oligomeric chain extender. The composition also often exceeds a threshold of 65° C. in heat deflection temperature. Use of an impact modifier further improves the industrial versatility of the heat resistant PLA composition.
