Preparation of cassava starch grafted with polystyrene by suspension polymerization.
Cassava starch grafted with polystyrene (PS-g-starch) copolymer was synthesized via free-radical polymerization of styrene by using suspension polymerization technique. Potassium persulfate (PPS) was used as an initiator and water was used as a medium. The graft copolymer was characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, thermal gravimetric analysi...
متن کاملThe spherical deformation model.
Miller et al. (1994) describe a model for representing spatial objects with no obvious landmarks. Each object is represented by a global translation and a normal deformation of a sphere. The normal deformation is defined via the orthonormal spherical-harmonic basis. In this paper we analyse the spherical deformation model in detail and describe how it may be used to summarize the shape of star-...
متن کاملFabrication of black printing toner through in situ polymerization: An effective way to increase conversion
Styrene-acrylate copolymer was synthesized in presence of carbon black through heterogeneous polymerization. The percentage of monomer conversion was measured by gravimetric method, also PSA, SEM, DSC and GPC were used for studying the particle size and particle size distribution, morphology, thermal properties and molecular weight, respectively. As well as color properties were characterized b...
متن کاملMICROSTRUCTURE AND MECHANICAL PROPERTIES OF THE ULTRAFINE-GRAINED COPPER TUBE PRODUCED BY SEVERE PLASTIC DEFORMATION
In this paper, cyclic flaring and sinking (CFS) as a new severe plastic deformation (SPD) method was employed to produce the ultrafine grain (UFG) copper tubes. The extra friction has eliminated in the CFS method that provided the possibility for production of longer UFG tubes compared to the other SPD methods. This process was done periodically to apply more strain and consequently finer grain...
متن کاملEBSD characterization of nano/ultrafine structured Al/Brass composite produced by severe plastic deformation
In the present work, nano/ultrafine structured Al/Brass composite was produced by accumulative roll bonding (ARB) up to eight cycles. The evolution of grain refinement and deformation texture and their effect on the mechanical properties were investigated. It was observed that by increasing the ARB cycles, due to the difference in flow properties of the metal constituents, brass layers necked, ...
