Abstract	Abstract. The effect of constant viscosity natural rubber (CVNR) prepared with hydrazine dihydrochloride was studied, The results showed that the relation of dependence of tC10 and tC90 on temperature followed the rule below: CVNR> NR a;the sensitivity of tC10 increment to tC90 increment due to increasing of cure temperature followed the rule below: NR>CVNR; The relation of MH0 were as follows: NR>CVNR. Introducation CVNR is prepared by the method of adding viscosity stabilizer into fresh NR latex. The CVNR with difference Mooney viscosity can be obtained through adding various viscosity stabilizers. For example[1] CVNR with low Money viscosity can be obtained through adding hydroxylamine hydrochloride or hydroxylammonium sulphate, CVNR with medium Money viscosity can be obtained through adding aniline or semicarbazide hydrochloride, CVNR with high Money viscosity can be obtained through adding aniline or hydrazine hydrate. CVNR is prepared with the same natural rubber latex and the same production method of coagulating and processing as that of NR, so the molecular structures of CVNB and NR are similar. The main difference between NR and CVNR is that CVNR contains hydroxylamine hydrochloride
