Abstract
The processes of regeneration of collagen-like structure were studied during gelation of gelatin in irradiated systems (thermically unsoluble and soluble gels) by the methods of measuring the optical rotation changes and of measuring the viscosity (η) and density (ϱ) product value of the system.
The kinetics of mutarotation process was considered as a simple transition of coil→helix and the order of this reaction was established to ben=3 both for unirradiated gelatin and for radiation modified systems. A complex process of re-formation of collagen-type structure was considered as a sum of three parallel first order reactions. The constant rates of these reactionsκ 1,κ 2 andκ 3 are independent of the degree of radiation crosslinking of gelatin system.
From these studies it has been concluded that the irradiated gelatin does not change the kinetics of re-formation of collagen-like structure. The contents of this structure decreases both in gelatin irradiated in solution and in the form of gel.
