  • Polylactic acid resin composition and additive for polylactic acid resin
    Patent number: 9290613
    Abstract: Provided is a polylactic acid resin composition which has excellent flexibility and heat resistance without decreasing a biomass degree. The polylactic acid resin composition includes a polylactic acid and a branched polylactic acid having at least three branched chains composed of a polylactic acid in the molecule can be obtained. This polylactic acid resin composition is very superior due to the following reasons: the resin composition has excellent flexibility because plasticization is accelerated; the resin composition has excellent heat resistance because crystallization is accelerated; and the resin composition is effective in protection of the global environment and measures against fossil resource depletion because the resin composition is derived from a recyclable resource.
    Type: Grant
