“…From studies of other blend systems involving the same or similar interacting groups, ,− as well as that in the previous paper, extensive and perhaps virtually complete proton transfer from SSA to the amine moiety, leading to ionic grafting, is expected. This is normally verified by infrared analysis.…”

Complexes of Polystyrene Ionomers with Butyl Acrylate Oligomers (Heterografts)

Monodisperse tert-butyl acrylate (tBA) oligomers of several lengths, functionalized at one end by a tertiary amine, were ionically grafted to lightly sulfonated polystyrene. Despite the oligomers being immiscible with the polystyrene matrix, dynamic mechanical analysis of the blends indicates only a weak phase separation effect, and the polymer is plasticized moderately. However, the blends (studied up to 30 wt %) are translucent, suggesting phase separation on a larger scale. A possible explanation is given in terms of nonspherical tBA domains subject to a hard-wall effect coupled with interfacial ionic interactions as well as ester−acid interactions. Evidence for the latter was noted in the infrared spectra.

“…Architectures other than linear chains can also be prepared via ionic interactions or simple metal coordination. Weiss and co‐workers studied supramolecular graft copolymers formed by ionic bonds or transition metal coordination (ion‐dipole), e.g., hemi‐telechelic amino terminated PIP/SPS (acid or zinc salt) and telechelic PBD with Cu‐sulfonate groups/SPS with random vinyl pyridine groups . Similarly, Orfanos et al grafted hemi‐telechelic sulfonated PS or sulfonated PIP to poly(vinyl‐2‐pyridine) using ionic bonds.…”

Ionomers are polymers with bonded ionic species that are used under conditions where the salt groups are in a condensed state. This Feature Article discusses the state of our understanding of ionomers and the historical applications of these nanostructured polymers. It also discusses modern methods for synthesizing new ionomers and describes a number of relatively new applications for ionomers and the potential use of these materials in contemporary technologies, including, shape memory and selfhealing materials and supramolecular polymer systems.

“…Specifically, a metal coordination complex was used that involved a blend of zinc-neutralized carboxyl-terminated polybutadiene (CTB) with poly(styrene- co -4-vinylpyridine) (PSVP). Similar polystyrene/polydiene elastomer blends with transition-metal or ionic interactions have been previously studied, − though not as shape memory materials. Weiss and Sasongko studied graft copolymers produced from ionic interactions or transition-metal complexation between the zinc salt of sulfonated polystyrene and amine-terminated polyisoprene.…”

Carboxyl-Terminated Polybutadiene–Poly(styrene-co-4-vinylpyridine) Supramolecular Thermoplastic Elastomers and Their Shape Memory Behavior

Aiming at an easy-processing metallo-supramolecular polymer which possesses the shape memory property and large deformation ability, we designed a simple metal coordination complex: the blends of zinc-neutralized carboxyl-terminated polybutadiene and poly(styrene-co-4-vinylpyridine) (PSVP). The two polymers are tightly bound due to the metal coordination interactions between Zn 2+ ions from carboxyl-terminated polybutadiene and the pyridine group of the PSVP. The elastomer had reasonably good mechanical properties and was thermoplastic. Improvements in mechanical properties of the blends were realized in the rheology analysis compared with a blend without the introduction of the zinc salt. Small-angle X-ray scattering characterization showed that the microstructure of the elastomeric blend consisted of microphase-separated glassy nanodomains of principally PSVP, which served as cross-link junctions that were connected with polybutadiene chains. The elastomer exhibited good shape memory properties for large deformations, and its shape recovery efficiency could reach 81% in the first cycle and could reach 97% ± 1% in the following seven cycles.
