| 英文摘要 | Trimethylsilyl hydroxypropyl cellulose (tms-hpc) was synthesized from hydroxypropyl cellulose and hexamethyldisilazane in dimethyl formamide. the structure of tms-hpc was characterized by infrared spectroscopy, h-1 nmr and c-13 nmr. the obtained tms-hpc achieved solubility in a variety of organic solvents, such as chloroform, acetone, and xylene so that the lyotropic liquid crystal mesophase can be formed in concentrated acetone. the critical concentration (c*) in acetone confirmed by plm photographs is approximately 36%. the relationship between the structure and solubility was analyzed using xrd. with the partial protection technique of the hydroxyl group via the tms group and the solubility of tms-hpc in organic solvents and the easy deprotection of tms groups, a new amphiphilic biodegradable graft poly(e-caprolactone) (pcl) with water-soluble hpc as a backbone was obtained by homogeneous graft copolymerization. the structure of the graft copolymer (hpc-g-pcl) obtained was confirmed by h-1 nmr.
