## Abstract Waterβsoluble hydroxypropyl chitin (HPC) derivatives were prepared by the reaction of chitin with propylene oxide in homogeneous conditions using a dimethylacetamide/5% lithium chloride solvent system. The reaction conditions for a proper substitution of the hydroxypropyl group were an
Chitin-p-toluenesulfonate(tosyl-chitin) was prepared homogeneously in lithium chloride-N,N-dimethylacetamide (LiC1/DMAc). In this solvent system, the side reaction of O-acetylation often occurred by solvolysis of p-toluenesulfonyl(tosyl) chloride. The utilization of strong base either triethylamine
## Abstract Chitin/polycaprolactone (PCL) blends were prepared by meltβblending of chitin and PCL with varying amounts of chitin. Thermal analysis of DSC, DMTA, and FTIR were used to characterize the blends. Results showed that increases in the amount of chitin did not cause a decrease in either th
