摘要：This research used ammonium chloride at doses of 0%,0.15%,0.30% and 0.45% with 0% dose, 0.15%,0.30% and 0.45% while formic acid and liquid smoke coagulants. The objective of this research is to determine the effects of the addition of additives (NH4Cl) and the type of coagulants on the quality slab degradation. The observed parameters were the value of dry rubber content (%),initial plasticity (Po), plasticity retention index (PRI),ash content (%),volatile matter (%) and Mooney viscosity. The results showed that doses ammonium chloride and coagulants affected to the value of dry rubber content (%),initial plasticity (Po),plasticity retention index (PRI),ash content (%),volatile matter (%) and Mooney viscosity. The treatment dose 0.45% ammonium chloride with coagulant has the best combination treatment reason it produced slab with dry rubber content 46.517%,initial plasticity 45,plasticity retention index 94,ash content 0.278%,volatile matter 0.604% and Mooney viscosity 72..
