In order to synthesis of skin beauty culture materials. We have studied the graft modification of amino group bearing β-chitin and β-chitosan derivatives, acetometoxyvinylketone(AMVK) was prepared and characterized by IR, 1H-NMR, and elemental analysis. acetometoxyvinylketone(AMVK) was graft onto N-succinyl-chitosan(NSC) in an aqueous solution using an ammoniumpersulfate (APS) as an initiator. Evidence of grafting was obtained by comparison of IR spectra of NSC and the grafted copolymer as well as solubility characteristics of the products. and, This natural polymer can use a medical care or biogical joint material. Variations of grafting efficiency with reaction time. temperature, concentration of initiator and monomer had been investigated. |
