Bio-based diblock copolymers prepared from poly(lactic acid) and natural rubber. Synthesis and purification of poly(l-lactic acid) using a one step benign process. Huihui Zhang, Gesheng Yang, Xiangbing Wang, Huili Shao, Xuechao Hu. Characterization of a homologous series of d , l -lactic acid oligomers; a mechanistic study on the degradation kinetics in vitro. Systematic comparison of oligomer spectra led to the identification of a neighboring effect which was shown to be linearly additive. Lactic acid gives a doublet signal at 1.42 ppm in the spectrum and acetic acid a singlet signal at 2.09 ppm, whose area is used to determine the concentration of these compounds. Influence of lactic acid-grafted multi-walled carbon nanotube (LA-g-MWCNT) on the electrical and rheological properties of polycarbonate/poly(lactic acid)/ LA-g-MWCNT composites. Baptista.
