Results of the present study as obtained from XRD, TEM, SEM, TGA, CLD (chemical crosslink density) and
tensile properties show that low dosages of kaolin modified with a solution of Phosphorylated Cashew Nut
Shell Liquid prepolymer (PCNSL) in toluene could act as potential nano-reinforcing fillers for natural rubber
(NR), as evidenced by improvements in filler dispersion, thermal stability and tensile properties of the
vulcanizates.
