Diblock amorphous topological structure of a filled vulcanizate network made of natural rubber (NR) and Emulsion Butadiene Rubber (EBR) was found. These blocks differ in the transition temperatures about 200掳C. Dual transitions of such rubbers have been assigned as a motion of the mixed soft ...
The effects of radiation-induced crosslinking on the physical arrangement of macromolecules in molten state natural rubber (NR) were examined. Three NR samples with doses of 0, 300, and 550 Mrad were studied based on differential radial distribution function (DRDF) curves derived from wide-angle...
In this work, the potential of wheat bran (WB) as a cellulosic filler for development of biocomposites based on natural rubber (NR) was evaluated. Wheat bran is a solid by-product of food industry, which can be applied as a low-cost, eco-friendly and cellulose-rich biofiller. However, ...
Summary Natural rubber, produced by coagulation of the latex from the tree Hevea brasiliensis , is an important biopolymer used in many applications for its outstanding properties. Besides polyisoprene, latex is rich in many nonisoprene components such as carbohydrates, proteins and lipids and thereby...
The silica nanoparticles were produced during the graft copolymerization through hydrolysis and condensation, i.e., sol–gel reaction; hence, they linked to the natural rubber particles. The nanomatrix structure was observed by transmission electron microscopy, in which the natural rubber particles of ...
Also, experimentation had been conducted on sample of sandwich panels using Hammer test process and the natural frequencies of the same were obtained. It was found that the results obtained from the analytical method using a standard platform have been in good agreement with the other approach....

natural rubber to obtain the pure monomer, which he namedisoprene. He determined isoprene's vapor density and molecular formula, and he showed that it polymerizes to a rubbery product—an observation that led to the notion that rubber is a linear polymer of isoprene, proposed in 1910 by ...

A relationship between viscoelastic properties and morphology of the nanomatrix-structured material, in comparison with that of the island-matrix structured material, in which the nanomatrix structure and island-matrix structure were formed by graft-polymerization of styrene onto natural rubber latex, was...
