Study on reparation of Blends Based on Poly(vinyl Chloride), Nitrile-butadiene Rubber, Natural Rubberand Polyethylene

Tóm tắt

The blends based on polyvinyl chloride (PVC), nitrile-butadiene rubber (NBR), natural rubber (NR) and polyethylene (PE) were made by three different methods. The mechanical properties of these blends in dependence of mixing time and temperature were characterized. The result showed that the two-step blending method, where PVC and NBR were first mixed together and then blended with NR and PE, is the best one to prepare blends with high mechanical properties.
