Thermal scanning rheological analysis

The miscibility of HDPE/LLDPE blends was also studied using differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMTA), rheological analysis, excimer fluorescence analysis, and transmission electron microscopy (TEM). Lee et al. (43) studi blends of HDPE (121,000 an 6.8 PDI)... [Pg.87]

Epoxidized oils were also used to modify PLA Ali et ah (2009) reported that its use as a plasticizer to improve flexibility. Thermal and scanning electron microscope analysis revealed that epoxidized soybean oil is partially miscible with PLA. Rheological and mechanical properties of PLA/epoxidized soybean oil blends were studied by Xu and Qu (2009) Epoxidized soybean oil exhibited a positive effect on both the elongation at break and melt rheology. Al-Mulla et al. (2010b) also reported that plasticization of PLA (epoxidized palm oil) was carried out via solution casting process using chloroform as a solvent. The results indicated that improved flexibility could be achieved by incorporation of epoxidized palm oil. [Pg.34]

In Reference 107, the effect of grafting of a polar group (MAH) onto LDPE chains and the chemical modification of clay particles with 2,6-diaminocaproic acid (L-lysine monohydrochloride) to produce nanocomposites with a matrix composed of a ternary blend of PEs (LDPE, LLDPE, and HDPE) was studied in detail. X-ray diffraction was used to determine the exfoliation degree of the clay. Morphological features were revealed by scanning electron microscopy and thermal analysis disclosed the thermal stability of the samples. Comparative analyses of the mechanical (under tension) and rheological properties of the nanocomposites were carried out as well. [Pg.592]

In Chapter 15, Kok describes how thermal analysis techniques can play a key role in examining the rheological behaviour of crude oils. For crude oil samples with different contents of wax, differential scanning calorimetry, thermomicroscopy and rheometry provide excellent... [Pg.8]

The ISPC formulation stability was monitored by rheological measurements. Thermal analysis of cured paint films for the control paints and ISPC systems was conducted by differential scanning calorimetry (DSC) measurements. Electrochemical... [Pg.44]

Measurement of Physical Properties. The dynamic rheological properties were measured by RDS-7700 with the concentric parallel plates. The thermal properties were measured with a Du Pont Thermal Analysis 2000 equipped with a 910 DSC. The fractured surface was observed by Hitatchi scanning electron microscope S-510. The tensile properties were measured by Instron tensile tester. [Pg.121]

Thermogravimetric Analysis to study the thermal properties. Scanning Electron Microscope and Transmission Electron Microscopy to analyze the morphology of the materials, Atomic Force Microscopy to carry out a surface analysis and Dynamic Mechanical Analysis (DMA) to evaluate the mechanical properties, etc. Also, it is important for the study of such properties as rheology and X-ray diffraction.

ILs have been recently evaluated as non-volatile plasticizers and as external or internal lubricants in several polymers including PVC [3], PMMA [4] and polyamides [5]. In this article, an amorphous PL A (polylactide) polymer is blended with two phosphonium-based ILs at various ratios by melt-blending, solution casting and a microencapsulation technique in order to investigate polymer/IL miscibility and its role in the development of a modified polymer with novel rheological, mechanical and thermal characteristics. Results of thermogravimetric analysis, differential scanning calorimetry, capillary rheometry, batch mixer torque measurements and optical microscopy are discussed. [Pg.1730]
