Cross-linking reaction of poly(4-vinylpyridine) cylindrical microdomains of poly(alpha-methylstyrene)-block-poly(4-vinylpyridine) films and characterization of soluble ribbon-like nanopolymers
The ribbon-like nanopolymers were prepared by the cross-linking reaction of poly(alpha-methylstyrene)-block-poly(4-vinylpyridine) (PMS-block-P4VP) diblock copolymer films exhibiting P4VP cylindrical microdomains with the vapour of I,4-dibromobutane in the solid state. It was indicated from the transmission electron microscopy (TEM) and the small-angle X-ray scattering (SAXS) that these cross-linked products had a structure of ribbon-like nanopolymers. It was found from the curve fitting on the static light scattering (SLS) intensity that such nanopolymers were in agreement with the conformation of the Gaussian model.
