✦ Synopsis

Polymerization of acrylamide in aqueous medium in the presence of gelatin has been carried out by the mutual method in air. All attempts to separate graft copolymer from the homopolymer and unreacted gelatin were unsuccessful as all the components were soluble in water. Hence the mixture comprising unreacted gelatin, homopolymer, polyacrylamide (PAAm), and the graft copolymer of gelatin and PAAm is referred to as the gelatin-g-PAAm composite. Solution properties of the composite with respect to viscosity, conductivity, and ultrasonic velocities were studied and the results were compared with those of PAAm prepared under identical conditions.
