Abstract
The graft copolymerization reaction between nylon fibers and ethylene oxide monomer has been studied extensively In the presence of alkaline catalysts, namely sodium hydroxide and potassium carbonate. A strong alkaline catalyst, sodium hydroxide, was found to be very effective In Increasing graft add-on at lower temperatures and in less time during the hydroxyethylation reaction on nylon. The mechanism of the graftin g reaction has been postulated.
