微生物凝固天然橡胶加速贮存期间分子量与P_O和PRI的变化研究

Variation of Molecular Weight, P_o and PRI of Natural Rubber Coagulated by Microorganisms During Accelerated Storage

对微生物凝固天然橡胶在加速贮存过程中分子量,PO和PRI的变化进行了研究,结果表明:随着贮存时间的增加,微生物凝固天然橡胶的分子量逐渐增大,PO值也随之增大,而PRI值则逐渐减小。PO与分子量成正比关系,PRI与分子量成反比关系。

The variation of molecular weight, Po and PRI of natural rubber coagulated by microorganisms during the accelerated storage was studied. The results showed that the molecular weight and Po increase with the increment of storage time, while the PRI reduces with the increment of storage time during accelerated storage. Po had a fine positive relationship with the molecular weight, but PRI had a negative relationship with the molecular weight.
