Effect of Grafting Conditions on NR-s-g-HFMA Copolymer and its Thermal Stability

Abstract

<p>Skim natural rubber (NR-s) is solidified by skim natural rubber latex. NR-s is often evaluated to low grade natural rubber because of its many bad properties such as poor resistance to aging. In order to improve the NR-s comprehensive property, fluorinated groups were incorporated into NR-s molecular chain by grafting via solution polymerization method. The grafted copolymer was characterized and the effects of conditions on grafting ratio and grafting efficiency were investigated. The thermal stability are also examined.</p>
