Modification of elastic poly(lactic acid) by radiation-induced crosslinking

Nagasawa, Naotsugu; Tamada, Masao; Kanazawa, Shinichi*; Hayasaki, Toshikatsu*

Poly(lactic acid), PLA was irradiated using electron beams in the presence of triallyl isocyanurate at 5 phr concentration as crosslinking agent. The crosslinked PLA, of which heat resistance was improved, is applied on flexible and elastic materials by addition of plasticizer or immersion in plasticizer. The elastic PLA material has several advantages such as high holding plasticizer, heat resistance at 80 $^{circ}$ C and transparency. It is therefore proven that crosslinking technology is beneficial to expanding application of soften PLA.
