Dynamic light scattering (DLS) has been used to explore the properties of asymmetric styrene-isoprene (SI) block copolymers in concentrated solutions. Concentrations were always well below those necessary to access the order-disorder transition in neutral good solvents. The samples include SI(10-50)
Dynamic light scattering behaviour in the form of periodic oscillating correlation functions has been found from measurements on both physically and chemically crosslinked hydrogels. The former were aqueous methyl cellulose at the thermal gelation temperature and the latter were poly(N,Ndimethylacry
