51. Soft Vesicles Formed by Diblock Codendrimers of Poly(benzyl ether) and Poly(methallyl dichloride)
The synthesis of a block codendrimer (g3-PBE-b-g3-PMDC), composed of a third-generation poly(benzyl ether) (PBE) monodendron and an aliphatic polyether (PMDC) monodendron is reported. In THF/diiospropyl ether (1:1) the PMDC block functions as a "hydrophilic" block, while the PBE acts as a "hydrophobic" block. The codendrimer can form interdigitated layers leading to vesicl...

47. Alternating crystalline-amorphous layers in hybrid block copolymers of linear poly(ethylene glycol) and dendritic poly(benzyl ether)
In the present work, we have studied the crystalline morphology of hybrid di- and triblock copolymers consisting of linear poly(ethylene glycol) (PEG) and Fréchet-type monodendrons of poly(benzyl ether). The linear blocks can crystallize to form spherulites under supercooling condition. Using atomic force microscopy and small-angle X-ray scattering method we found alternating crystalli...

Salt-Induced Micelle Behavior of Poly(sodium acrylate)-block-Poly(N-isopropylacrylamide) by ATRP
Temperature- and pH-sensitive diblock copolymers PAANa75-b-PNIPAMm are prepared by a
combination of reverse and normal ATRP in aqueous solution at room temperature. The block
copolymer is also stimuli-sensitive with respect to salt in the aqueous solution, and forms
spherical star-like micelles with a PNIPAM core
and an expanded PAANa shell for PAANa75-b-
PNIPAM76 as well as spherical crew-ou...

Synthesis, Characterization and Properties of Degradable Poly(L-lactic acid)/Poly(butylene terephthalate) Copolyesters Containing 1,4-Cyclohexanedimethanol
High molecular weight copolyesters based on poly(butylene terephthalate) (PBT) as rigid aromatic segments and poly(L-lactic acid) (PLLA) as degradable aliphatic segments were synthesized via polycondensation of terephthalic acid (TPA), 1,4-butanediol (BDO), 1,4-cyclohexanedimethanol (CHDM) and poly(L-lactic acid) oligomer (OLLA).Through tailoring the molar ratio of diols (BDO and CHDM), the effect...

Investigation of endocytosis and cytotoxicity of poly-d,l-lactide -poly(ethylene glycol) nano/micro- particles in osteoblast cells
polymer particles present a promising approach for intracellular
delivery of drugs, proteins, and nucleic acids. Poly-d,l-lactide-poly(ethylene glycol) (PELA)
copolymers with different weight ratios of polyethylene glycol (PEG) were used as drug carriers
in the present study. PELA particles entrapped with fluorescein isothiocyanate (FITC) as
a fluorescent marker were formulated using a double ...

Dynamic Rheological Behavior and Morphology of Poly(trimethylene terephthalate)/Poly(ethylene octene) Copolymer Blends
The dynamic rheology and morphology of
poly(trimethylene terephthalate) and maleic anhydride
grafted poly(ethylene octene) composites were investigated.
A specific viscoelastic phenomenon, that is, a second
plateau, appeared at low frequencies and exhibited a
certain dependence on the content of elastomer particles
and the temperature. This phenomenon was attributed to
the formation of an a...
