In continuation of a previous investigation on the small‐angle scattering of rayons in the dry and water‐swollen condition, a number of samples are investigated in lithium hydroxide solutions of increasing concentration up to 5 N, in which considerably higher degrees of swelling can be reached. In samples showing an intensity maximum in the water‐swollen condition, the locus of this maximum shifts to smaller angles upon further swelling in LiOH solutions, to disappear in 5 N solutions. Samples exhibiting neither a maximum nor an inflection point in no case yield straight Guinier plots even at the highest degree of swelling attained.
