【 摘 要 】

Crosslinking density and rheometric behaviour of natural rubber (NR)/chloroprene rubber (CR) blends with blend ratios from 0.0 to 100.0% rubber were investigated utilizing the semi efficient vulcanization. The degrees of crosslinking density were calculated using FloryRehner equations. The rheometric properties were tested by utilizing moving die curemeter (MDR 2000). From the overall results, cure and scorch times of the rubbers blends enhanced with increases the CR content. Whilst, the maximum values of torque difference and crosslinking density were performed by the rubbers blend with the 50/50 blend ratio.
