Abstract
Graft polymerisation of acrylamide (Aam) to loomstate cotton fabric using a KMnO4 H2N-C-NH2 system was studied under a variety of conditions. The polymerisation reaction was studied with respect to graft yield, homopolymer total conversion and graft efficiency. Results indicated that the polymerisation reaction was found to depend upon the concentrations of potassium permanganate, thiourea and acrylamide, as well as upon the pH of the reaction medium, reaction time and temperature of polymerisation. Based on detailed investigation of these parameters, the optimal grafting was obtained with 0.04 g/1 kMnO4; 0.06 g/1 thiourea; pH 3; temperature 80°C and time 60 minutes.
