## Abstract Four novel Schiff‐type chitosan (CTS)‐crown ethers were synthesized through a reaction between NH~2~ in CTS or crosslinked chitosan (CCTS) and CHO in 4′‐formylbenzo‐crown ethers, and four secondary‐amino‐type CTS‐crown ethers were prepared through the reduced reaction of NaBH~4~, resp

✦ Synopsis
Abstract
The Michael reaction of chitosan with acrylic acid was carried out successfully, even in water alone as the reaction medium. As a consequence of its good solubility in water, the reaction product, N‐carboxyethylchitosan, showed excellent biodegradable properties with standard activated sludge.

## Abstract The main techniques developed to characterize chitosan are recalled. The interaction of chitosan with oppositely charged surfactants was investigated giving very important surface activity effects. A few chemical modifications are described and the new properties obtained are mentioned:
## Abstract The mono‐filaments (> 10 m in length) of chitosan and the blends of chitosan‐collagen, chitin‐collagen and chitin‐silk fibroin were wet‐spun. The mono‐filaments were chemically __N__‐modified with each of __n__‐fatty acid anhydrides, intra‐molecular carboxylic anhydrides, fragrant aldeh
