摘　　要：采用丙烯酰胺、2-丙烯酰胺基-2-甲基丙磺酸、甲基丙烯酸、苯乙烯磺酸为主要单体,合成一种四元聚合物降滤失剂。对聚合物的性能进行了评价。结果表明,基浆中含有质量分数为1%聚合物的条件下,250℃滚动16h后仍有降滤失效果。在饱和盐水基浆中具有降滤失效果,能将滤失量控制在可接受的范围内。同时,该聚合物可显著改善基浆的流变性。The quadripolymer filtrate reducer was synthesized using acrylamide,2-acrylamide-2-methyl propane sulfonic acid,methyl acrylic acid,styrene sulfonic acid as main monomers.The evaluation of the performance of the polymer shows that in the 1% of polymer amount,250℃ after rolling 16 hit still have the effect of reducing filtration.In the saturated salt water slurry,the filtration loss can be controlled within an acceptable range.The polymer can also significantly improve the rheological properties of the pulp.
