Abstract
PREVIOUS workers1 have shown from X-ray measurements that organo-clay complexes may be formed by certain organic compounds entering between the montmorillonite sheets. In the course of investigating the interaction of various high polymers and montmorillonite, a new kind of complex has been observed, involving the edge faces of the clay crystals only. This type of complex, tentatively called a ‘peripheral’ complex, has the same c-axis spacing as pure montmorillonite when dry, but differs markedly in its swelling pattern in dilute salt solutions.
