摘　　要：通过研究聚脲流变剂相对分子质量大小和结构对其流变性和回复性的影响,确定最合适的分子结构和相对分子质量大小,设计出抗流挂性最佳的聚脲流变剂,通过试验表明,理论相对分子质量在2 700左右的线性结构聚脲流变剂具有很好的抗流挂效果。The influence of polyurea rheological agent size of molecular structure on its rheological property and resilience were studied, the most appropriate size of the molecular structure and molecular weight were determined, the best polyurea rheological agent were designed, through the test showed that when theoretical molecular weight linear structure was about 2 700, the polyurea rheological agent had good resistance to flow effect.
