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...
متن کاملButadiene and Styrene Risks
The control of cell proliferation by gastrin has been investigated in a rat pancreatic tumour cell line, AR4-2J. Exogenous gastrin, 10-12 to 10-8 M, stimulated cell growth of thymidine-synchronised AR4-2J cells cultured over 48 h in serum-free medium. Cell lysates of AR4-2J cells contained an average of 4.5 and 3.5 pg gastrin per 106 cells, when grown in serum-supplemented or serum-free media, ...
متن کاملThermo-gravimetric Analysis (TGA) of combustion and gasification of Styrene-Butadiene Copolymer (SBR)
An investigation has been initiated to determine the effects of various atmospheres (6.9% 02iN2, 21 % 02iN2 (air), 30% 02iN2, 3% H2iN2 and pure N2) on the efficiency of gasifying or combusting rubber waste to produce synthesis gas or generate steam or power. This paper reports on the findings from a series of TGA experiments at various heating rates on styrene-butadiene copolymer (SBR), which i...
متن کاملElectro - mechanical properties of triblock copolymer styrene - butadiene - styrene / carbon nanotube composites for large deformation sensor applications
Thermoplastic elastomer/carbon nanotube composites are studied for sensor applications due to their excellent mechanical and electrical properties. Piezoresisitive properties of tri-block copolymer styrene-butadiene-styrene (SBS)/ carbon nanotubes (CNT) prepared by solution casting have been investigated. Young modulus of the SBS/CNT composites increases with the amount of CNT filler content pr...
متن کاملPreparation and Characterization of Heterogeneous PVC-Silica Proton Exchange Membrane
Heterogeneous proton exchange membranes (PEM) are synthesized using the dry phase inversion technique. The casting solutions are prepared by dispersing a finely ground cation exchange resin particle in N,N-dimethylacetamide (DMAc) solution of polyvinyl-chloride (PVC). Results show that ion exchange capacity is increased with the addition of 1 %-wt nanosilica (from 0.14 to 0.27 meq/g) while it i...
