    Modification of poly(lactic acid) by radical grafting for application in advanced polymeric materials

  • Original language description

    Post-reactor modification of poly(lactic acid) (PLA) was realized by free-radical grafting of PLA with itaconic anhydride (IAH) which are both derived from renewable resources. The reaction was initiated using 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane(L-101). The influence of reaction conditions on IAH conversion, thermal properties and material structure was investigated. Hydrolytic scission of backbone or IAH homopolymerization was observed as undesired reactions. Evidence of grafted IAH and relation between reaction conversion and IAH/L-101 ratio were confirmed by acid-base titration, FTIR spectroscopy and NMR spectroscopy. Thermal properties and crystallization behavior of neat PLA and modified PLA (i.e, Tg, Xc) were determined as a function ofmonomer conversion by temperature modulated scanning calorimetry - TMDSC. Molecular weight and polydisperzity of grafted PLA samples were determined by GPC, contact angle was measured to predict adhesion properties.
