In this thesis, monomer with unsaturated double bond was firstly synthesized byreacting acryloyl chloride with bifunctional monomer. Such synthesized monomer ormonomer with initial unsaturated double bond was used to prepare linear polymericmaterials by free radical polymerization. A series of new degradable space polymerswith acylamino bond were subsequently synthesized using diisocyanate as thecross-linker.

749Mg/ml and 0.778u/ml, respectively. 5. Study on the viscosity changes of reaction solution and analysis of enzymatic hydrolysis products by TLC, HPLC showed that ChiB was an endo-type cleavage enzyme. It decreased viscosity of reaction solution, hydrolyzed β-(1, 4) glucosidic bond of chitosan, acted on GlcN-GlcN, GlcN-GlcNAc and/or GlcNAc-GlcN glucosidic bond. It did not act on GlcNAc-GlcNAc glucosidic bond. Hydrolysis products of chitosan were composed of chitotriose, chitotetraose and chitopentose.
