摘　　要：部分水解聚丙烯酰胺(HPAM)高分子线团上的羧基与交联剂柠檬酸铝(AlCit)发生分子内交联反应,形成交联聚合物线团(LPC).研究了交联聚合物溶液(LPS)在压差为0.0981MPa下通过0.4,1.2,2.0和3.0μm孔径的核微孔滤膜的过滤速度,判断了LPC的尺寸大小.对于黏均相对分子质量为1.4×107、质量浓度为100mg/L的HPAM与AlCit反应后,其形成的LPC大小在400～900nm.The carboxylic group of polymer coil within partially hydrolyzed polyacrylamide(HPAM) and the aluminum citrate (AlCit, crosslinker) induced intramolecular crosslinking reaction and linked polymer coils(LPC) were formed. The filtration velocity of linked polymer solution throught nuclepore film with the pore diameter of 0.4,1.2,2.0 and 3.0 μm was measured on the pressure of 0.098 1 MPa. The size of LPC is determined accurately. The diameter of the LPC in solution(the relative molecular weight of HPAM is 1.4×10~7, the concentration of HPAM is 100 mg/L) was less than 900 nm, and the diameters of some LPC were more than 400 nm.
