shows the mechanical properties of the NRL/PS and TWL/PS blends prepared from the solution casting. Comparing of NRL and TWL, the tensile strength (TS) of TWL is higher due to the crosslinked molecules (TWL is from WL, compounds used in the dipping process). It is well known that crosslinks can improved the material strength (Asaletha et al., 1999, Rooj et al., 2011); thus, it is not surprising that TWL shows higher TS than NRL, which without crosslinks. When NRL was blended with PS
