LDPE and poly(1-butene) blends: Morphology, crystallinity and rheological properties
In this work, the compatibility and crystallinity of low density polyethylene (LDPE) and polybutene-1 (PB-1) blends were studied. Various blends of LDPE/PB-1 containing 5, 10 and 20 wt.% PB-1 were prepared in a corotating twin-screw extruder and characterized by scanning electron microscopy (SEM), shear oscillation rheology and wide-angle X-ray diffractometry (WAXD). A matrix-droplet morphology...
متن کاملPreparation of AlPO4-5 nano-pore crystals: Effect of alteration in precursor gel preparation on the morphology of crystals
Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...

متن کاملHYDRATION BEHAVIOR OF Na-SMECTITE CRYSTALS SYNTHESIZED AT HIGH PRESSURE AND HIGH TEMPERATURE
-Hydration behavior of Na-smectite crystals synthesized at a pressure of 5.5 GPa and temperatures of 1400"-1500~ was examined by X-ray powder diffraction at various relative humidities (RH) in the range of 0-100%. The basal spacing of the Na-smectite crystal increased stepwise with increase in RH. The reflections observed were only normal reflections of a single or dual hydration states of smec...
متن کاملSynthesis of zeolite NaA nano-crystalls; effect of synthesis parameters on crystallinity and crystal size
Abstract In this work hydrothermal synthesis of zeolite NaA crystals with a composition of Al2O3:aSiO2:bNa2O:cH2O was investigated. Effects of SiO2/Al2O3, Na2O/Al2O3 and H2O/Al2O3 ratios and crystallization temperature and time were studied on crystallinity and crystal size of zeolite NaA crystals. It was tried to understand the interactions between these parameters. The crystal species o...
