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.

Vietnam belongs to the region of tropical climate with high temperature and moisture, especially very high violete radiation exposure. Under these conditions the properties of elastomeric alloys made from waste rubber powder and polypropylene using peroxide as an initiator were messured. Using the dynamic stabilizing method the influence of the composition and the nature of the components on the alloy stability was estimated.
