摘要
Abstract
The water-soluble microcrosslinking copolymers ( PADM) were synthesized by the micellar free radi-cal copolymerization technique,using acrylamide (AM) as the basic monomer,2-acrylamide -2-methyl-propane sulfonic acid ( AMPS) as the solubilizing monomer and divinyl benzene ( DVB) as the crosslinking monomer,and the copolymer structures were characterized by IR spectrum and 1 H-NMR spectrum. The effects of the AMPS and DVB feed,NaCl concentration,temperature and shear rate on solution properties of PADM were studied,and the re-sults showed that the PADM copolymer displayed good thickening and salt-resistant behavior due to the incorpora-tion of DVB into the coplymer. The apparent viscosities of 0. 15 g/dL PADM with the feed of 0. 7%( mol%) DVB in pure water and 7. 5g/dL NaCl solution were 376. 9mPa·s and 155. 4mPa·s at 45℃,respectively. In addtion,the PADM copolymer exhibited good antishearing and heat-resisting properities.关键词
