2.2. Preparation of the NR-g-CStThe NR-g-CSt was prepared following the methodoutlined in our previous work (Riyajan, Sasithornsonti,& Phinyocheep, 2012). Before use, the CSt sampleobtained was dried in an oven at 50◦C for 48 h. A CStsolution was prepared by dissolving CSt in distilled watercontaining 2% (v/v) of K2S2O8at 85 ± 3◦C for 1 h. After cooling, thegelatinized CSt was mixed with 10 g of 0.5% w/w K2S2O8solution,and stirred at 60◦C for 45 min to obtain a modified CSt. Then 86 gof 60% dry rubber content NR latex was mixed with 500 g of the10% modified CSt in the presence of Triton X-100 and stirred at60◦C for 3 h.
