由交联聚电解质组成的离子交换树脂曾用于缓释制剂,但结果不尽满意。作者介绍了一种新的疏水性聚电解质——聚甲基丙烯酸甲酯和甲基丙烯酸共聚物(PMMA/MAA)的合
Ion exchange resins consisting of crosslinked polyelectrolytes have been used in sustained release formulations, but the results have not been satisfactory. The authors describe a new hydrophobic polyelectrolyte - a combination of polymethylmethacrylate and methacrylic acid copolymer (PMMA / MAA)
