Degree of crystallinity for polymer blends with PLA was calculated on the basis of melting enthalpy, according to the formula [16]:
The ballot measure, which proposed adding a new position, fiscal officer, to the PLA Board, was approved by an overwhelming 97% majority.
"I'm very pleased that the joint venture has started-up the second-largest PLA bioplastics plant in the world," says Bernard Pinatel, president refining and chemicals at Total.
While the breaking elongation of PLA exhibited little change from -20[degrees]C to 40[degrees]C, it sharply increased at temperatures over 40[degrees]C.
PLA solution was then modified with two types of multiwalled carbon nanotubes (CNTs) (Nanostructured and Amorphous Materials Inc., USA), in the concentration of 1% (wt.) with respect to the PLA content.
For FTIR analysis, compatibilized and uncompatibilized PLA/PCL (70/30) blends were separated into components using N,N-dimethyl formamide (DMF), which dissolves PLA but not PCL [6, 23].
The enthalpy--the thermodynamic quantity equivalent to the total heat content of a system--of crystallization decreased from 23.15 joules per gram to 14 joules per gram with the addition of starch to PLA. This indicated that the starch granules might restrict the molecular motion of the PLA matrix, resulting in decreased crystallinity.
La viscosidad intrinseca del PLA sin procesar (PLAsp) y del PLA procesado en diferentes equipos y condiciones, del PLA procesado primero por extrusion a 200[grados]C y luego por inyeccion a 200[grados]C (PLAp1) o a 230[grados]C (PLAp2), y de los compuestos con sepiolita natural (PLA/Sep) y montmorillonita (PLA/Cloi-30B) se determinaron por viscosimetria capilar en solucion usando cloroformo.
Also, Corbion and Succinity, a joint venture between BASF and Corbion Purac, are promoting a model biopolymer compound of PLA and PBS (polybutylene succinate) that offers strong heat resistance, balanced mechanical properties, biodegradability and a high biorenewable content.
PLA was used as a reinforcing polymer at different concentrations (10 to 50 wt%), whereas NPCC and talc acted as a nucleating agent were fixed at 2 phr, respectively.
The addition of starch into PLA is one of the most promising efforts due its abundant and cheap biopolymer particularly cassava starch since it is the fifth most abundant starch crop produced in the world and the third most important food source for inhabitants of tropical regions.
