通过在羧甲基纤维素（CMC）上接枝丙烯酰胺和二甲基二烯丙基氯化铵，制备了一种新型的两性纤维素衍生物（CAD）。对CAD作为粘土水化抑制剂在油田钻井液中的应用性能进行了考察，结果表明，CAD具有抑制粘土水化的性能，对低固相钻井液具有较好的造浆性能。研究了CAD抑制粘土水化的机理。CAD的吸水-水合性能不仅与阳离子、阴离子含量和分子量有关，还与CAD链上的阳离子-阴离子缔合有关。John Wiley & Sons，Inc. J.应用聚合物Sci. 70：921-926，1998年
A new ampholytic cellulose derivative (CAD) was prepared by grafting acrylamide and dimethyldiallylammonium chloride on carboxymethyl cellulose (CMC). The performance of CAD applied as a clay-hydration inhibitor in oil field drilling fluid was examined; the results showed that CAD had a hydration inhibitive property with better mud-making performance for low-solid mud. The mechanisms of the CAD inhibition of clay hydration were studied. The inhibiting-hydration performance of CAD was found to depend not only on cation, anion content, and molecular weight, but also on the cation–anion association in CAD chains. © 1998 John Wiley & Sons, Inc.
