Cross-linking reaction of segregated microdomains formed by diblock copolymer films

Polystyrene- block-poly(4-vinylpyridine) (PS- block-P4VP) (P4VP block, 36 mol%) was prepared by anionic polymerization. Three types of morphologies (sphere, cylinder and lamella) were controlled by changing the casting solvents. Subsequently, the cross-linking reaction of P4VP spherical, cylindrical...

More Information
Summary:Polystyrene- block-poly(4-vinylpyridine) (PS- block-P4VP) (P4VP block, 36 mol%) was prepared by anionic polymerization. Three types of morphologies (sphere, cylinder and lamella) were controlled by changing the casting solvents. Subsequently, the cross-linking reaction of P4VP spherical, cylindrical or lamellar microdomains was carried out with the vapor of 1,4-dibromobutane in the solid state. The morphologies and solution properties of the cross-linked products were studied by electron microscopy, small-angle X-ray scattering and static and dynamic light scattering.
