摘要
Abstract
A new type of amphiphilic derivative of carboxymethylchitosan (CMCHS) was prepared by reaction of CMCHS with p-nonylphenyl glycidyl ether.The structure of the resulting derivatives,i.e.,(2-hydroxyl-3-p-nonylphenoxy) propyl-carboxy-methylchitosan (HNP-CMCHS) had been identified by UV and IR spectroscopy.They are water-soluble and have surface activity,which is related to the degree of substitution and the added electrolyte in the solution.In the presence of NaCl,two transitions appeared on the surface tension-concentration plots,that means the possibility of the formation of intramolecular micelle.It was also found that it need a long time for the surface tension of the derivative solutions to get a equilibrium value and the time is related to the derivative concentration,degree of substitution and added electrolyte of the solution.关键词
