【摘要】 通过自由基聚合合成了超低分子量的聚丙烯酰胺,再用甲基丙烯酸缩水甘油酯对其进行改性,制备了一种新型无毒水溶性聚丙烯酰胺灌浆材料。与普通丙凝浆材相比,该改性聚丙烯酰胺是一种性能优异的环保型灌浆材料。更多还原

【Abstract】 A polyacrylamide with extra-low molecular weight was synthesized through free radical polymerization and then modified with glycidyl methacrylate to form a new non-toxic water soluble polyacrylamide grouting material. The comparision between polyacrylamide and acrylamide indicates that the polyacrylamide is an environmentally -friendly grouting material with excellent performance.更多还原
