Compatibilization of polycarbonate/poly (ethylene terephthalate) blends by addition of their transesterification product
In this study, poly carbonate (PC) and poly (ethylene terephthalate) (PET) were reactive melt-blended under two different conditions to produce PC/PET copolymers. For each condition, samples were taken at specified mixing times representative a specific structure of copolymers and each one employed to physically compatibilize a PC/PET blend with a fixed composition. Reactive blending and copoly...
متن کاملTransesterification by Reactive Distillation for Synthesis and Characterization of Biodiesel
Rising world fuel prices, the growing demand for energy, and concerns about global warming are the key factors driving renewed interest in renewable energy sources and in bioenergy. Nowadays, the world energy demand has increased significantly due to the global industrialization and increase of population. As a result, the current limited reservoirs will soon be depleted at the current rate of ...
متن کاملMonoglyceride synthesis by glycerol transesterification on solid bases
Introduction Glycerol is the main byproduct of biodiesel production. Nowadays, glycerol surplus is becoming a matter of environmental and economic concern. Therefore, new ideas to convert glycerol in more valuable compounds are needed. Monoglyceride (MG) synthesis by glycerol (Gly) transesterification with fatty acid methyl esters (FAME), Figure 1, is an attractive option to transform this biom...
متن کاملSynthesis and Properties of Plasticized Sulfur-Montmorillonite Nanocomposites by Melt-Blending
Plasticized sulfur/montmorillonite nanocomposites were prepared by the melt-blending method and the dispersion of montmorillonite (MMT) and the mechanical properties of the nanocomposites were studied. Natural sodium montmorillonite (NaMMT) and organically modified montmorillonite (OMMT) were used as filler. Scanning electron microscope (SEM), X-Ray powder Diffraction (XRD...
متن کاملThe Role of Transesterification on the Miscibility in Blends of Polycarbonate and Liquid Crystalline Copolyester
Transesterification mechanisms and rate in blends of polycarbonate (PC) and random liquid crystalline polyester copoly(oxybenzoate-p-terephthalate) at molar ratio 40/60 (P46) were studied through a five-component diad analysis and with 13C and 1H-13C nuclear magnetic resonance spectroscopy. It was found that the ester-ester interchange in the two polymers took place within 15 min when the blend...
