Synthesis of heteroarm star polymers comprising poly(4-methylphenyl vinyl sulfoxide) segment by living anionic polymerization
A series of 3-arm ABC and AA'B and 4-arm ABCD, AA'BC and AA'A''B heteroarm star polymers comprising one poly(4-methylphenyl vinyl sulfoxide) segment and other segments such as polystyrene, poly(α-methylstyrene), poly(4-methoxystyrene) and poly(4-trimethylsilylstyrene) were synthesized by living anionic polymerization based on diphenylethylene (DPE) chemistry. The DPE-functionalized polymer...

Synthesis of well-defined polymers grafted onto fumed silica by chain exchange reaction and highly pure block copolymers thereby
pubs.rsc.org/en/content/articlelanding/2010/cc/c0cc02135k
Radical-induced addition-fragmentation processes were efficiently used for surface modification of fumed silica, and Z-supported solid CTAs could be reused in presence of excess sacrificial thermal initiator.

Facile synthesis of hyperbranched and star-shaped polymers by RAFT polymerization based on a polymerizable trithiocarbonate
pubs.acs.org/doi/abs/10.1021/ma1024736
Facile synthesis of hyperbranched and star polymers on the basis of S-(4-vinyl)benzyl S’-propyltrithiocarbonate (VBPT) was described. RAFT copolymerization of VBPT with vinyl monomers such as methyl methacrylates (MMA), styrene (St), methyl acrylate (MA) and tert-butyl acrylate (tBA) afforded hyperbranched copolymers with variable branch length and deg...

23. Ordered structure of thermotropic liquid crystalline polymers. 2. Observation of annihilation kinetics of wedge disclinations
The isothermal annihilation kinetics of wedge disclinations in the fully liquid crystalline state were investigated using thin film specimens of a thermotropic liquid crystalline copolyester prepared by a solution-cast method. The as-cast films which are vitrified, homogeneous and amorphous were first subjected to a temperature jump to appropriate temperatures and the coarsening of the liquid...

Design and Synthesis of Fluorescence “Turn-on” Chemosensors based on Photoinduced Electron Transfer in Conjugated Polymers
A new approach to fluorescence “turn-on” chemosensors based on a photoinduced electron transfer (PET) strategy involving conjugated polymers has been developed. Two new conjugated polymers dea-PPETE and tmeda-PPETE were synthesized and characterized. These two polymers use diethylamino and N,N,N‘-trimethylethylenediamino as receptors, respectively, on a poly[p-(phenyleneethylen...

[MACROMOLECULES] Synthesis and Lectin Recognition of Glyco Star Polymers Prepared by "Clicking" Thiocarbohydrates onto a Reactive Scaffold
Glycopolymers with a four-arm star architecture were prepared from poly(vinyl benzyl chloride) (PVBC) star polymers as reactive scaffold and 1-thio-beta-D-glucose sodium salt. The star polymer was prepared via RAFT polymerization using 1,2,4,5-tetrakis(thiobenzoylthiomethyl)benzene as a rate-retarding RAFT Latent at a polymerization temperature of 120 degrees C. The occurrence of known side reacti...
