摘　　要：凝胶化过程是增塑粘剂向PVC糊树脂颗粒内部扩散的过程。文中将不同增塑剂含量的PVC糊的粘度与凝胶化过程中的粘度进行了对比,导出了增塑剂扩散动力学曲线。The gelation of PVC paste is a process during which the plasticizer diffused into the particles of PVC paste resin. This paper introduces dynamics curves of diffusion process of plasticizer by means of contrasting the viscosity of PVC pastes varied in amount of plasticizer with the variation of viscosity during gelation process.
