摘要
本工作应用透射电子显微镜研究了丙烯酰胺/2-丙烯酰胺基十六烷磺酸铵无规共聚物(AM/AMC_(16)SNH_4)的形态结构.给出共聚物在水溶液中具有伸展网状结构,并存在一定程度的疏水基因间的缔合作用.是一种在耐盐性和储存稳定性方面有明显改善的新型改性聚丙烯酰胺.
The morphology of copolymers of acrylamide and ammonium-2-acrylamidohexadecane (AM/AMCi?SNH4) has been studied by TEM. The copolymer molecule in water is extended to form filamentous structure. Aqueous solutions of the copolymers showed much better viscosity retention in salt solutions, temperature and aging stability than those of partially hydrolyzed polyacrylamides.
