Abstract

A variety of styrene-isoprene block copolymers, covering a wide range in composition, have been investigated using small angle neutron scattering (SANS). Investigations of hydrogenous copolymers enabled the domain separation and packing to be obtained, it was found that spherical domains form a face centred cubic structure and cylindrical domains a hexagonally close packed arrangement. The relation between interdomain spacing and copolymer molecular weight is,

$${{d}_{{spheres}}}{\text{ }}\alpha {\text{ }}{{M}^{{O.48}}}{{d}_{{cylinders}}}{\text{ }}\alpha {\text{ }}{{M}^{{O.7}}}{{d}_{{lamellar}}}{\text{ }}\alpha {\text{ }}{{M}^{{O.52}}}{\text{ }}$$
