摘　　要：介绍了制备阴离子型高分子量聚合物胶乳的技术路线和合成工艺，评价了合成产品的性能。用AMPS作阴离子单体，通过与一至两种非离子单体反乳液共聚反应，制得了固相含量高、分子量高、在酸液中能速溶的阴离子型高分子量聚合物胶凝剂。该产品具有耐热酸水解、耐热稀释、抗剪切、抗盐降解性能。Gelled acid 15 often used to enhance the stimulation in low permeable reservoir.This Paper Presents a methpd of preparing and compounding a new anionic gellant for using in the acid fluids.AMPS 15 chosen as the anionic monomer，and by its compounding with one or two kinds of non一ionic invert emulsions，a polymer gellant with high solids content and molecu-lar weight is prepared.The gellant is instant soluble in acid，and it has good thermal stability，anti一shearing property and salt resistance，etc
