“…Zhang et al prepared cylindrical polymer brushes featuring dendritic side chains via an iterative anionic polymerization protocol for polyisoprene‐ block ‐polystyrene (PI‐ b ‐PS) . Polybutadiene (PBd) segments were grafted with polystyrene (PS) by anionic polymerization after hydrosilylation of the PBd backbone with pendant chlorosilane moieties . Very recently, the Hirao group reported on the preparation and analysis of precisely grafted polystyrene‐ block ‐polyisoprenes, via iterative anionic polymerization and a graft reaction using diphenylethylene (DPE) functional groups …”

Common stimuli include temperature, pH, light, redox reagents, and electrical fields. [16][17][18][19][20][21][22][23] Block copolymers featuring polyvinylpyridine (PVP) segments have attracted enormous attention due to their ability to undergo microphase separation, metal ion complexation, nanoparticle complexation, as well as participate in hydrogen bonding. [24] Stamm and co-workers have reported extensively on poly(styrene-block-(4-vinylpyridine)) (PS-b-P4VP) as a system. For example, they have reported on the influence of hydrogen bonding for poly(styrene-block-(4-vinylpyridine)) (PS-b-P4VP) for microphase separation, [25] the use of sacrificial PS-b-P4VP networks as carbon precursors, [26] the use of PS-b-P4VP as polymer templates for the preparation of highly ordered arrays of metallic nanodots, [27] and the preparation of P4VP-based block copolymers for helically arranged nanoparticle complexation in cylindrical domains. [28] Besides their structure formation capabilities, PVPs have been used as pH-responsive homopolymers, or as reversibly addressable segments in smart block copolymer architectures featuring protonated pyridinium moieties. [16] For example, Li et al. reported on the pH responsiveness of Au@PVP particles, and their application as pHresponsive bimetallic catalysts. [29] Furthermore, responsive P4VP-based cross-linked films have been used as pH sensors and as surfaces with controllable surface wettability. [30] The group of Eisenberg has also reported on the morphological changes in PS-b-P4VP micelles as a function of pH range. [31] Additionally, multi-stimuli-responsive block copolymers featuring a poly(2-vinylpyridine) (P2VP)-containing block segment were investigated in thin films, [32] as micelles in water, [33,34] and as smart nanocapsules. The latter have been advantageously used for the triggered release of different payloads from the capsules' interior. [21,35] As another impressive example, PSb-P4VP was the first polymer under investigation for creating integral asymmetric membranes with highly uniform pore sizes. [36] The complexation of the P4VP block segments with copper(II) ions was utilized for a stabilization of the PS-b-P4VP micelles in solution and hence a high reproducibility of uniform pore structures was achieved. [37,38] Besides copper(II) salts, other transition metals like nickel(II), cobalt(II), and iron(II) are also capable of influencing the self-organization of Anionic PolymerizationsFunctional block copolymers are a highly relevant material platform for many potential applications in fields of nanolithography, drug delivery, and separation technologies. Here, poly(2-vinylpyridine) (P2VP)-grafted diblock copolymers consisting of polystyrene-block-polyisoprene (PS-b-PI) backbone are synthesized via an iterative anionic grafting-to polymerization strategy. P2VP macro anions having molar masses of 1.1, 3.6, and 9.9 kDa are grafted to PS-b-PI block copolymers featuring 37 mol% 1,2-polyisoprene moieties. Prior to the grafting-to strategy, the PS-b-PI is subjected to pl...

“…The selectivity can be improved, however, by end-capping polystyryllithium with diphenylethylene 7,12) . Alternative routes based on the use of polystyrene and polybutadiene chains bearing chlorosilyl groups as reactive polymer backbone have also been explored respectively by Roovers 13,14) and Cameron et al 15) We have recently described the functionalization of polystyryllithium chains by a series of organic derivatives bearing a chloroalkyl ether or a chloroacetal function 16) . Indeed, the chloroethyl ether function is particularly efficient to selectively anchor specific groups at the end of polystyrene chains 17,18) .…”

SUMMARY: The grafting of polystyryllithium onto chloroethyl ether functions of poly(chloroethyl vinyl ether) (PCEVE) chains is a selective reaction which allows the complete substitution of chloride of CEVE units by polystyrene (PS) chains. Since the PCEVE polymer backbone and the PS grafts can be prepared by living cationic and anionic polymerization, respectively, it is possible to synthesize PCEVE-g-PS polymers possessing both a backbone with controlled dimensions and an adjustable number of branches of precise length. This procedure was applied to the synthesis of a series of linear and macrocyclic comblike PCEVE-g-PS based on the use of linear and cyclic PCEVE as reactive backbone, respectively. The synthesis, the characterization and the solution properties of these linear and cyclic comblike polymers are reported.

“…Post backbone modification can be carried out by epoxidation, hydrosilylation [38,39], metallation/grafting [40] or other methods. Backbone functionalized solution SBRs containing up to 5% of either hydroxy [41] or carboxy [42] functional groups have also been reported recently.…”

. Dr. Hsu currently has 107 US Patents and more than 50 referenced publications in the area of organomeallic chemistry, inorganic chemistry, polymer chemistry and tire elastomers. He has presented several seminars at universities and scientific meetings, and also chaired several scientific meetings on tire polymers. Abstract Hydrocarbon elastomers bearing polar functional groups at their chain ends or at both chain ends can greatly reduce the hysteresis of a tire compound and thus improve rolling resistance and fuel economy. These functional elastomers can be easily prepared via living anionic polymerization techniques. However, to prepare an elastomer with more than two functional groups in the same polymer chain, especially along the polymer backbone, a more elaborate and costly process is normally required. To facilitate the in-chain functionalization of tire elastomers, we have developed a series of new styrenic and E0-methyl styrenic monomers containing various amine functional groups starting from relatively inexpensive divinylbenzene or diisopropenylbenzene.These functional monomers allow one to prepare novel functionalized tire elastomers containing any number of amine functional groups at any location within the polymer chain via anionic co-polymerization with any conjugated diene or styrene monomer. More importantly, polymerization can be carried out over a wide temperature range, even at the elevated temperatures normally used for commercial production of tire elastomers. The preparation of these new functional monomers and their co-polymerization with diene monomers will be presented. The physical properties of these novel functionalized polymers will be compared to their conventionally prepared counterparts in carbon black and silica filled compounds.
