| Abstract: | Four styrene-isoprene two-block copolymers of high molecular weight (Mw5 × 105–2.5 × 106) containing ～50% polystyrene have been prepared in a high state of purity. Their optical properties were studied in solution by transmission and diffraction techniques. It is shown that these properties can be related to the sizes of the domains present due to phase separation. |
