【摘要】 <正>高吸水性树脂,是一种含有羧基、羟基等强亲水性基团并轻度交联的功能高分子材料。它能吸收相当于自身质量几百倍甚至上千倍的水,且不易渗出。壳聚糖具有良好的生物相容性、抗菌性和可降解性等优异性能,在制备生理卫生材料用品的方面,高吸水性树脂方面具有广阔的前景。本文以壳聚糖、马来酸酐为原料,通过酰化反应合成水溶性的N-马来酰化壳聚糖。以N-马来酰更多还原

【Abstract】 Superabsorbent resin based on the monomers maleic anhydrid（MA）,acrylic acid（AA） was prepared by solution polymerization using a ammonium sulfate and NaHSO₃ as initiator,N-maleyl chitosan as cross-linking agents.Effects of process parameters such as the concentrations of monomers,cross-linker, neutralization degree of AA,and m_AA/m_MA on the absorbency of superabsorbent resin were discussed. Under the optimal conditions,the absorbency of superabsorbent resin from distilled water was 1560.42g/g.更多还原
