Differntial Thermal Analysis of Propylene-Styrene Copolymer

Study of structure and thermal properties of styrene-butylacrylate ‎copolymer with OMMT nanocomposite emulsions

‎(St-co-BA) polymer through montmorillonite (MMT) nanocomposite emulsion is prepared by ‎in situ intercalative emulsion polymerization of styrene (St), butyl acrylate (BA) in the ‎presence of organic modified montmorillonite (OMMT) with different OMMT contents (0, ‎‎0.5, 1.0, 1.5, and 2.0 wt%). The synthetic compounds are characterized by FTIR, XRD. The ‎nanocomposite emulsions are characterize...

Polycyclic Aromatic Hydrocarbon (PAH) formation in thermal degradation of Styrene Butadiene Copolymer (SBR)

This study has been initiated to quantify the release of the Polycyclic Aromatic Hydrocarbon (PAH) species from Styrene· Butadiene Copolymer (SBR) during gasification. The identification and quantification has been detennined experimentally using Gas Chromatography/ Mass Spectroscopy (GC/ MS) coupled to a Thenno-Gravimetric Analysis (TGA) unit. SBR samples were pyrolysed in a TGA unit in a Nz a...

Synthesis and Saxs Characterization of Sulfonated Styrene-ethylene/propylene-styrene Triblock Copolymers

Thermal Analysis of Acrylonitrile/Acrylic Acid Copolymer Dendrigrafted with Citric Acid

Thermal analysis of acrylonitrile/acrylic acid P(AN/AA) copolymer films containing 5%, 10% and 20% acrylic acid dendrigrafted with citric acid (CA) is examined using differential scanning calorimetry (DSC) with various heating rates, thermogravimetry (TGA) and derivative thermogravimetric analysis (DTG). Also, the effect of carboxylic acid on thermal stabilization of the P(AN/AA) copolymers, wh...

Three-dimensional study of cylindrical morphology in a styrene-butadiene-styrene block copolymer

When a block copolymer undergoes microphase separation, well ordered microstructures result which give the copolymer unique thermal and mechanical properties. In relating these properties quantitatively to the microstructure, and in devising models for the phase separation, theoreticians have always invoked highly idealized structural elements. However, variations in the actual microstructure m...
