Biomaterials 2010: Cytotoxicity and in vivo tissue compatibility of poly(amidoamine) with pendant amino butyl group as a gene delivery vector
To design successful polymeric gene delivery vehicles with good biocompatibility and highly efficient gene transfer ability is one of the great scientific challenges in modern gene therapy. Poly(amidoamine) with pendant aminobutyl group (PAA-BA) has been proved to exhibit high transfection efficiency against bone marrow stromal cells (BMSCs) in vitro. In this work, based on prev...

Fractionation of Poly(vinyl acetate) and the Phase Behavior of End-Group Modified Oligo(vinyl acetate)s in CO2
Poly(vinyl acetate) (PVAc) is an inexpensive, high-tonnage bulk commodity polymer which, unlike most vinyl polymers, is moderately biodegradable. PVAc has been shown to exhibit anomalously high soly. in CO2 with respect to other vinyl hydrocarbon polymers. Understanding the phase behavior of PVAc in CO2 and its variation with structure is very important for its potential application as...

Photoinduced Holographic Phase Gratings Buried in Azobenzene Side-Chain Polymer Films with A Chiral Group
An optically active polymer(PM1) containg zaobenzene moieties with a chiral group (s-2-methyl-butyl) was synthesized by homopolymerization of monomer,4-[2-(methacryloyloxy)ethyloxy]-4`-(s-2-methyl-1-butyloxycarbonyl) azobenzene,using the free radical polmerization method. The polymer dissolved in tetrahydrofuran(THF) could be easily proessed into high optical quality films. The optical anisotropy ...

High optical transparency and low dielectric constant of organosoluble polyamide based on 1, 2-Bis-(4-amino-2-trifluoromethylphenoxy) benzene
关键字：trifluoromethyl group,polyamide,solubility,dielectric constant
A novel fluorinated polyamide was prepared from an aromatic diamine containing trifluoromethyl group (–CF3), 1,2-bis(4-amino-2-trifluoromethylphenoxy)benzene, and aromatic dicarboxylic acids(OBA) by using phosphorylation polycondensation. The fluorinated polyamide was&...

Acetylenes with multiple triple bonds: a group of versatile An-type building blocks for the construction of functional hyperbranched polymers
关键字：Acetylene polymerization; Hyperbranched polymers; Functional materials
ABn-type molecules are widely used as monomers for the synthesis of hyperbranched polymers. Because the mutually reactive A and B groups are liable to self-oligomerize, the monomers are difficult to prepare and handle. We have&nbs...
