The rheological behavior of centrifuged and creamed natural rubber latex concentrates and the effect of surface-active agents such as casein, polyvinyl alcohol (PVA), sodium alginate, and sodium carboxymethylcellulose ( NaCMC ) were studied at different shear rates and temperatures. The study showed

Based on the results of bound-rubber determination, Monsanto rheometric studies, solvent swelling, measurement of physical properties, and infrared spectroscopic studies, it is revealed that epoxidized natural rubber (ENR) and hard clay interact chemically to form Si-O-C bond during high-temperature
## Abstract This study sought to synthesize an __in situ__ epoxidized natural rubber (NR) from 20% dry rubber content latex stabilized by nonionic surfactant, 5 phr of Terric 16A16, in the presence of hydrogen peroxide and formic acid at the temperature of 50ยฐC. The molar ratios of H~2~O~2~ and HCO
