摘要：
The present paper described the constant viscosity modification of natural rubber cup gel with hydroxylamine hydrochloride (HH) and alkyl hydrazine compounds (OP). Then, the influence of the constant viscosity agent HH and OP on the Mooney viscosity, relative molecular weight, initial plasticity (P0) and plasticity (PRI) of the crude rubber was analyzed by Mooney viscometer, gel permeation chromatography and Wallace plastometer. The experimental results indicate that hydroxylamine hydrochloride(0.2~0.6) and OPRHAZ(0.2~0.6) can effectively control the Mooney viscosity of natural rubber cup gel below 60, and the initial plastic value (P0) of natural rubber is more than 30. © 2019, Editorial Board of Polymer Materials Science & Engineering.
