摘　　要：本文研究了射流凝固天然橡胶在加速贮存过程中凝胶含量、相对分子量、P_0和PRI的变化。结果表明:随着加速贮存时间的延长,射流凝固天然橡胶的凝胶含量、相对分子量和P_0值增大,而PRI值却减小。P_0值与相对分子量成正比关系,PRI与分子量成反比关系。The variation of gel content,molecular weight,Po and PRI of Jet Coagulation Natural Rubber during accelerated storage was studied. The results showed that the gel content,the molecular weight and Po of natural rubber increase with the increment of storage time, the PRI of natural rubber reduces with the increment of storage time during accelerated storage.P0 had a fine positive relationship with the molecular weight, but PRI had a negative relationship with the molecular weight.
