| 摘要 |
Chitosan derivatives formed by glycoside bond of D-glucosamine and its derivatives modified with poly(oxyalkylene) oxide at beta -1,4 sites, in which the chitosan derivatives are expressed by Formula (1) where: n1+n2+n3>/=5, n1/(n1+n2+n3)</=0,2 and R1 is poly(oxyalkylene) group having an average degree of polymerization from 10 to 300. |
