A simple conductometric titration method is discussed for the determination of sulfhydryl groups in nonionic polymer networks, such as disulfide and alkylene sulfide crosslinked polycaprolactam fibers. The diffusion of the titrant into the crosslinked polymer is accomplished by swelling the network structure, thereby eliminating the necessity of destroying the crosslinks and/or breaking the polymer chains.
