  • The study on the relationship between compositions and mechanical properties of the blends based on poly(vinyl chloride) (PVC), butadiene-acrylonitrile rubber (NBR) and natural rubber (NR) has been carried out. The result shows that in the presence of NBR, which plays role of transition phase between the two incompatible polymers PVC and NR, the tertiary phase polymer blends having high tensile strength and elongation at break were obtained.

  • Presently, in mineral industry of Vietnam 2 types of spiral separators are employed: (i) 1200 mm-diameter type made of unplastized PVC (type A) and (ii) 600 mm-diameter type made of polymer composite (PC) and surface layer is chloroprene rubber (type B). In practice it has proven that type B has conductivity considerably higher than type A and easy movement resulting from smaller size.

  • Since the establishment of the conductive properties of intrinsic conductive polymers, a huge variety of basic and applied research has been carried out, involving different polymers, copolymers, blends, mixtures and composites. Thus, fundamental understanding of physical and chemical properties of these materials has been sought, while the applied aspects have advanced very rapidly, crossing the boundaries between disciplines. Today, the applications of conducting polymers in various fields such as neuroscience, nanotechnology and green chemistry, are easily found.
