ARTICLE ANNOTATION

quote
Graft copolymerization of acrylamide and methacrylamide with collagen in an aqueous solution in the presence of potassium persulfate as an initiator was carried out. The dependences of the graft copolymerization rate on the concentration of monomers, initiator and temperature were determined. A logarithmic dependence of the graft copolymerization rate on the monomer concentration at a constant initiator concentration and on the potassium persulfate concentration at a constant monomer concentration and at a constant temperature was constructed. The main kinetic parameters of the process were established using these dependences: the reaction order with respect to the concentration of monomers and potassium persulfate. The obtained parameters indicate the formation of both grafted and free chains of polyacrylamide and polymethacrylamide. Active grafting centers on collagen macromolecules are formed as a result of the interaction of potassium persulfate with collagen. In this case, some part of the potassium persulfate decomposes with the formation of free radicals, which initiate the homopolymerization of the monomer. The overall activation energy of the process was determined from the dependence of the logarithm of the graft copolymerization rate on the inverse temperature at constant monomer and initiator concentrations. The obtained values of the activation energy of graft copolymerization of both acrylamide and methacrylamide indicate that the process occurs under energetically favorable conditions.
