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.
