摘　　要：根据平衡溶胀理论,研究了溶胀法的试验条件及共混胶的硫化条件对硫化胶表观交联密度Vr值的影响。结果表明,采用溶胀法测定CIIR/BR共混硫化胶的Vr值具有稳定的溶胀规律和变化趋势,并对比分析了以氯仿和120#汽油为溶剂,测定共混硫化胶Vr值的方法特点。Based on equilibrium swelling theory,the vulcanization conditions of blend vulcanized rubber and test conditions of swelling method has been studied the impact on apparent crosslink density. The results show that apparent crosslink density Vrof CIIR / BR measured by the swelling method has stabilized swelling laws and trends,and the feature and characteristics of Vrdetermined by using chloroform and 120#gasoline as solvent have been comparatively analyzed.
