Analysis of the variation of molecular parameters of NR during vulcanization in the frame of the conformational tube model

The network structure of natural rubber (NR) achieved during vulcanization was analyzed using the model of rubber elasticity based on the tube concept, applied to the treatment of the stress-strain measurements. This theory allows the separation of constraint and crosslink contributions. Also, netwo...
