When thin films of natural rubber, gutta-percha, polybutadiene, and polybutadiene-styrene copolymers are deposited at the surface of aqueous acidified potassium permanganate, they undergo a surface reaction and spread spontaneously. A study of the products of this reaction has been made, and their surface characteristics are described. The reaction products are polyhydroxy derivatives of the polyolefins and are shown to form stable monomolecular layers at an air-water interface. The areas of the hydroxylated olefin residues have been determined, and their magnitude and orientation at the interface is discussed. The agreement between experimentally determined areas and theoretical areas (from established interatomic distances) is good. Results suggest that butadiene-styrene copolymers contain an appreciable number of blocks of contiguous styrene units.
