新型淀粉吸水剂HSPANS的合成及其吸水、保水性能的研究

STUDIES ON PREPARATION AND PROPERTIES OF WATER—ABSORPTION AND WATERRETENTION OF A NEW TYPE STARCH GRAFT COPOLYMER ABSORBENT HSPANS

合成了一种比现有淀粉接枝物吸水剂吸水性能更为优异的新型淀粉吸水剂——HSPANS。系统地比较了各种淀粉接枝物吸水剂的吸湿性、吸水性、凝胶保水性能,以及溶液的pH值、分散介质、温度以及压力等因素对淀粉接枝物吸水剂吸水、保水性能的影响. 吸水、保水性能比较结果为: HSPANS>HSPAN>>CLSPAANa>SPAMS>SPAM>

A new type of starch graft copolymer absorbent HSPANS has been prepared and its water—absoirbency is more better than these existing starch graft copolymer absorbents. The proparties of humidity—absorption, water—absorption and water—retention of these absorbents have been compared systematically. The effects of the pH value, dispersion medium, temperature and pressure on those properties were studied. The experimental results show that the order of the water— absorption and water—retention capacity of these absorbents is HSPANS>HSPAN>>CLSPAANa>SPAMS>SPAM>SMS.
