Poly-D-lactide

The phase space of the poly(ethylene-aft-propylene)-fr-poly(d, (-lactide) (PEP-fo-PLA) system was recently explored by Schmidt and Hillmyer [63]. All equilibrium symmetries I, C, S, and G were observed. The G morphology, however, existed in only a small region between the L and C in close proximity to the ODT (Fig. 12). [Pg.156]

Usual PLAs have two enatiomeric forms, PLLA and poly(D-lactide) (PDLA), which are synthesized from LLA and the D,D-isomer of lactide (DLA), respectively. It is well known that 1 1 mixture of PLLA and PDLA can form a stable stereocomplex (SC), which has a higher Tm and higher mechanical strength than either of homopolymers [261], We reported on the utility of SC formation to enhance the stability of nanogels. Monodisperse SC nanogels were obtained through the self-assembly of an equimolar mixture of Dex-g-OLLA and Dex-g-ODLA in a dilute aqueous solution. [Pg.93]

Furthermore for the formation of a stereocomplex which blends of poly(L-lactide) and poly (D-lactide) could be found the interesting phenomena. The PLA stereocomplex was found to possess a racemic crystalline structure, where PDLA and PLLA chains were packed side hy side with a D monomer unit to L monomer unit... [Pg.868]

Poly(lactic acid) has three typical optical isomeric forms (i) optically active and crystalliz-able poly(L-lactide) (i.e. poly(L-lactic acid) (PLLA)), (ii) optically active and crystallizable poly(D-lactide) (i.e. poly(D-lactic acid) (PDLA)), and (iii) optically inactive and noncrystal-lizable poly(DL-lactide) [i.e. poly(DL-lactic acid) (PDLLA)]. Of these isomeric polymers, PLLA is most frequently used because its production cost is lower due to its joint mass production of 1.4 X 10 metric tons per year by NatureWorks LLC, which is owned by Cargil... [Pg.171]
