Abstract
A sulfonic acid fibre was fabricated by graft copolymerization of p-styrenesulfonate to Vion KN-1 fibre using redox and peroxide initiating systems with a static exchange capacity of 2 meq/g. Use of a redox initiating system in graft copolymerization causes the formation of up to 20–50 wt. % homopolymer, while the mass of homopolymer deceases to 10–25% in peroxide initiation. Repeated graft copolymerization of the monomer remaining in the solution virtually does not increase the effective degree of conversion.
