Therefore, additives are used in combination, but most of the additives are petroleum-derived, so the biomass-derived characteristics of PLA are not fully utilized.<br \/>\nIn addition, although it is possible to improve the impact resistance and flexibility of polylactic acid using only biomass-derived materials such as polylactic acid and natural rubber,In general, polymer blends are incompatible in many cases, and it is difficult to expect to improve physical properties as designed.<br \/>\nTherefore, the inventor kneaded PLA with a biomass-derived material at a specific ratio by dynamic cross-linking and further devised it to improve impact resistance and flexibility.<\/p>\n<h3><strong>Data<\/strong><\/h3>\n<p>Addition of plasticizer improves impact resistance<br \/>\n(Approx. 30 times that of PLA alone)<\/p>\n<table style=\"border-collapse: collapse;
