NBR latex
3.By the oxidation-reduction system of hydrazine hydrate and hydrogen peroxide in the presence of copper catalyst, the hydrogenate experiments in latex are studied for the SBR, NBR and polyisoprene Their hydrogenated extent comes to 90 percent and 50 percent, separately The reason of the lower hydrogenated extent for the polyisoprene is mainly influenced by its structure The hydrogenated extent is also influenced by the particle-size of latex
