摘要： Natural rubber (NR) was coagulated using different methods, i.e., acid coagulation with acetic acid (A-NR), natural coagulation (N-NR), and microorganism coagulation (M-NR). The crosslink density, vulcanization properties, dynamic properties, and heat build-up were investigated. The results showed that M-NR had the highest crosslink density and fastest cure rate, and A-NR had the lowest crosslink density and slowest cure rate. The dynamic properties were measured using a rubber process analyzer, dynamic thermomechanical analysis and compression heat build-up tester; the results showed that the dynamic properties had a close relationship with the crosslink density. The loss factor was lowest for M-NR and highest for A-NR.
