Polyacrylamide grafted gelatin


There PAAm side chain, due to the molecular size increases,[link widoczny dla zalogowanych], so the viscosity increases; and reaction with the arch technology used to increase the number of monomers,[link widoczny dla zalogowanych], side chain will be longer, resulting in as shown in Figure l,[link widoczny dla zalogowanych], grafting reaction products viscosity with the increase of monomer. It was also noted that the grafting reaction of raw materials and products of gelatin R G. The viscosity of the solution with the pH value changes. About products and pH4.7 grafting reaction. The results also show that when the graft reaction product solution with enough concentration, this solution at room temperature and the gelatin is still the same with the Freezing ability, can form a gel. 4. Conclusion (1) K2s2O8 as initiator, was synthesized by four rubber / PAAm graft copolymer. (2) in the grafting process, the gelatin will occur a certain degree of degradation. (3) reaction products from the graft was significantly higher viscosity show that the gelatin / PAAm graft exists. (4) the graft copolymer still has the ability to isoelectric point and Freezing. * 122 * secret and Technology gelatin in September I994 concentration (c��.% 'S Yue Yi Shao device l06420l23 concentration (q,[link widoczny dla zalogowanych],% concentration (c��,% Figure 3 gelatin / monomer ratio is not the same time,[link widoczny dla zalogowanych], graft copolymer blends G and the relationship between viscosity and concentration of Fig.3Therel-don song ipbetweenflscoskl ~ sandc scorpionfish c cricket trano Sh�� ofgritcopo | ymerGandb�� eDdMtlITl-O Lang geljtIn / monomerratioc | s Sh�� mold device Volume 14, Indigo 3 Lee Sung rule: the gelatin grafted polyacrylamide l23 ��
