Radiation draft of N-methylolacrylamide in solid phase to cotton cellulose

The mechanism has been studied of solid phase radiation grafting N-methylolacrylamide to cotton cellulose which results in becoming crease-proof. The grafting was carried out in the air by exposure to Co60 gamma-rays at room temperature. It is shown that the process is initiated by cellulose macroradicals and inhibited by radical acceptors. A homopolimerization of methylolacrylamide occurs together with the grafting. For a 1 mrad dose there is a 60% yield of copolymer and a 10% one of homopolymer with 30% of unreacted monomer. An increase in the dose leads only to a slight increase in the homopolymer content. The grafting degree drastically decreases as the moisture content of exposed specimens increases and slightly increases with an increase in the dose rate for the same dose
