本文对HPAMMO40 0 0聚合物体系在动态情况下形成以分子间交联为主的体系的最低聚合物浓度进行了研究。通过实验发现用紫外分光光度计测量的聚合物 /Cr3 交联体系与对应的聚合物溶液的紫外差谱值得出的最低浓度 ,与通过粘度测量得出的最低浓度具有很好的一致性。在 6 5℃下聚交比为 10时研究得出的最低聚合物浓度为 6 0 0mg/L。
In this paper, the lowest polymer concentration of HPAMMO4000 polymer system which forms the main intermolecular cross-linking system under dynamic conditions was studied. It was found experimentally that the lowest concentration of UV difference spectrum between the polymer / Cr3 cross-linked system and the corresponding polymer solution measured by a UV spectrophotometer was in good agreement with the lowest concentration measured by viscosity measurement. The lowest concentration of polymer in the study at 6 5 ° C was 1060 mg / L.
