Poly(Llactide) (PLA) was blended with polypropylene (PP) at various ratios (PLA: PP ¼ 90 : 10, 80 : 20, 70 : 30,and 50 : 50) with a melt-blending technique in an attempt to improve the melt processability of PLA. Maleic anhydride (MAH)-grafted PP and glycidyl methacrylate were used as the reactive compatibilizers to induce miscibility in the blend. The PLA/PP blend at a blend ratio of 90 : 10, exhibited optimum mechanical performance. Differential scanning calorimetry and thermogravimetric analysis studies showed that the PLA/PP/MAH-g-PP blend had the maximum thermal stability with the support of the heat deflection temperature values. Furthermore, dynamic mechanical analysis findings revealed an increase in the glass-transition temperature and storage modulus with the addition of MAH-g-PP compatibilizer. The interaction between the compatibilizers and constituent polymers was confirmed from Fourier transform infrared spectra, and scanning electron microscopy of impact-fractured samples showed that the soft PP phase was dispersed within the PLA matrix, and a decrease in the domain size of the dispersed phase was observed with the incorporation of MAH-g-PP, which acted as a compatibilizer to improve the compatibility between PLA and PP.

Sustainable hydrogen transfer reactions without the use of expensive noble metals and toxic solvents is a challenging task. In this work, a process has been developed for selective hydrogenation of carbonyl compounds to corresponding alcohols.
