Synthesis of ABCD 4-Miktoarm star-shaped quarterpolymers by combination of the click chemistry with multiple polymerization mechanism.
Well-defined ABCD 4-Miktoarm star-shaped quarterpolymers of [poly(styrene)-poly(tert-butyl acrylate)-poly(ethylene oxide)-poly(isoprene)] [star(PS-PtBAPEO-PI)] were successfully synthesized by the combination of the ‘‘click’’ chemistry and multiple polymerization mechanism. First, the poly(styryl)lithium (PSLiþ) and the polyisoprene)lithium (PILiþ) were capped...

Synthesis and characterization of star graft copolymers with asymmetric mixed V-shaped side chains via click chemistry on a hyperbranched polyglycerol core.
The star graft copolymers composed of hyperbranched polyglycerol (HPG) as core and well defined asymmetric mixed ‘‘V-shaped’’ identical polystyrene (PS) and poly(tert-butyl acrylate) as side chains were synthesized via the ‘‘click’’ chemistry. The V-shaped side chain bearing a ‘‘clickable’’ alkyne group at the conjunction poin...

[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...

Synthesis, Characterization, and Thermal Properties of Dendrimer-Star, Block-Comb Copolymers by Ring-Opening Polymerization and Atom Transfer Radical Polymerization
Novel and well-defined dendrimer-star, block-comb polymers were successfully
achieved by the combination of living ring-opening polymerization and atom
transfer radical polymerization on the basis of a dendrimer polyester. Star-shaped dendrimer poly(e-caprolactone)s were synthesized by the bulk polymerization of e-caprolactone with a dendrimer initiator and tin 2-ethylhexanoate as a catalyst. Th...

Synthesis, Characterization, and Fluorescence of Pyrene-Containing Eight-Arm Star-ShapedDendrimer-Like Copolymer with Pentaerythritol Core
Novel and well-defined pyrene-containing eight-arm star-shaped dendrimer-
like copolymers were successfully achieved by combination of esterification,
atom transfer radical polymerization (ATRP), divergent reaction, ring-opening polymerization (ROP), and coupling reaction on the basis of pentaerythritol. The reaction of pentaerythritol with 2-bromopropionyl bromide permitted ATRP of styrene (St)...

Synthesis, characterization, and controllable drug release of dendritic star-block copolymer by ring-opening polymerization and atomtransfer radical polymerization
A series of well-defined dendritic star-block copolymers were successfully synthesized by combination of living ring-opening polymerization
(ROP) and atom transfer radical polymerization (ATRP) with the hydroxyl-terminated dendrimer polyester. Dendritic star-shaped poly(L-lactide)s
(PLLAs) were prepared by bulk polymerization of L-lactide (L-LA) with dendrimer polyester initiator and tin 2-ethyl...

Supramolecular Polyseudorotaxanes Formation between Star-Block Copolymer and a-Cyclodextrin: From Outer Block to Diblock Inclusion Complexation
A series of star-block poly(L-lactide)-b-poly(ethylene oxide) (SPLLA-b-PEO) copolymers were synthesized by ring-opening polymerization (ROP) and DCC chemistry. The inclusion complexes of SPLLA-b-PEO copolymers and a-cyclodextrin (a-CD) were prepared with two different methods. FTIR, 1H NMR, WAXD, DSC, and TGA indicate that a-CD only can be threaded onto PEO blocks in inclusion complexes of a-CD-SP...

Star-Shaped alkylated poly (glycerol methacrylate) reverse micelles: synthesis and evaluation of their solubilizing properties in dichloromethane.
Amphiphilic star-shaped polymers were synthesized by atom transfer radical
polymerization (ATRP). Four-, 5-, and 6-arm ATRP initiators were prepared and
used to polymerize glycidylmethacrylate. The resulting polymers were hydrolyzed to
yield poly(glycerolmethacrylate)s (PGOHMAs), and then partially esterified with
lauroyl or stearoyl chloride (40–60 mol % vs. hydroxyl groups). Alkylated ...

Aminated linear and star-shape poly(glycerol methacrylate)s: synthesis and self-assembling properties,
Over the past 10 years, polyglycerols and their structurally related analogs have received considerable attention in the biomedical field. Poly(glycidyl methacrylate) (PGMA) is a versatile polymer because its pendant epoxide groups can be opened with different functional groups to generate poly(glycerol methacrylate)s (PGOHMA)
derivatives. In this work, linear and star-shape PGMAs were synthesize...
