摘　　要：丁腈胶乳中引入羧基会对胶乳性能产生明显影响。探究不同羧基含量对胶乳粘度、粒径、结合腈含量、门尼粘度和物理机械性能的影响。实验结果表明,粒径和结合腈含量与羧基含量无关,粘度受羧基含量影响呈指数变化,门尼粘度和物理机械性能与羧基含量呈线性相关。The introduction of carboxyl groups into nitrile rubber latex has a significant impact on latex performance.This article explores the effects of different carboxyl content on latex related viscosity,particle size,bound nitrile con⁃tent,Mooney viscosity,and physical and mechanical properties.The experimental results show that particle size and bound nitrile content are independent of the carboxyl content,while viscosity varies exponentially affected by the car⁃boxyl content.Mooney viscosity and physical and mechanical properties are linearly related to the carboxyl content.
