"We propose to investigate a specific role of coplymers in micro- and macrophase separation and phase dissolution utilizing time-resolved light scattering, quasielastic light scattering and as complementary methods also speckle techniques, optical microscopy and scanning and transmission electron microscopy. The investigated systems include binary blends of a homopolymer A with a copolymer AB i.e. A/AB and ternary blends A/B/AB of homopolymers with copolymers (symmetric, asymmetric,random) in solid state, melt and in solutions, when adding of solvent is desirable to either enhance the dynamics of the system or to visualize the selected component of the mixture. The effort of investigators should lead to gathering of substantial new information about structure, dynamics and morphology of polymer blends during micro- and macrophase separation and phase dissolution and aboud the role of copolymers on these processes."@en . .
