Originální abstrakt
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 of monomer 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. Modified PLA could be used in industrial application, especially by chemical compatibilization of grafted PLA with other polymers or fillers coatings. Such processes based on reactive extrusion could form polymer blends or composites with combined properties of both blended materials.
