Abstract

Natural rubber latex waste (WL) was treated with natural rubber latex (NRL) prior to blend with polystyrene. Different
blend compositions of treated waste natural rubber latex (TWL) and PS were carried out through solution blending. Tensile
and tear properties were investigated. The compatibility improvement of the 70/30 TWL/PS blends was further investigated
using styrene butadiene rubber (SBR) and styrene graft natural rubber (SNR) as compatibilizer. The mechanical properties for
TWL/PS blends were improved at 15 phr of SNR.
