Crosslinked Styrene/divinylbenzene Network Systems
Differences in properties of pure metaand pure para-divinylbenzene crosslinked polystyrene and their sulphonated products have been correlated with probable network structural differences. The para-divinylbenzene copolymerizes more slowly than does the meta isomer to give a crosslinked copolymer which swells less, sulphonates less rapidly, and, when sulphonated, gives an ion exchanger which has...
متن کاملMulticompartmental Microcapsules from Star Copolymer Micelles
We present the layer-by-layer (LbL) assembly of amphiphilic heteroarm pH-sensitive star-shaped polystyrene-poly(2pyridine) (PSnP2VPn) block copolymers to fabricate porous and multicompartmental microcapsules. Pyridine-containing star molecules forming a hydrophobic core/hydrophilic corona unimolecular micelle in acidic solution (pH 3) were alternately deposited with oppositely charged linear su...
متن کاملSynthesis and Characterization of the Copolymer of Dodecyl Methacrylate/Styrene Containing an Amidine Functional Group
A copolymer of dodecyl methacrylate/styrene (DMA/St) containing the amidine functionality was synthesized and characterized. The one-step solution copolymerization process was carried out using a mixed solvent, high temperature, and a functional azo initiator, 2,2 -azobis[N,N -dimethylene isobutyramidine]. Copolymers with different compositions (DMA/St 10/1 to 1/2), molecular weight (Mn 2000–90...
متن کاملDegradable copolymer based on amphiphilic N-octyl-N-quatenary chitosan and low-molecular weight polyethylenimine for gene delivery
BACKGROUND Chitosan shows particularly high biocompatibility and fairly low cytotoxicity. However, chitosan is insoluble at physiological pH. Moreover, it lacks charge, so shows poor transfection. In order to develop a new type of gene vector with high transfection efficiency and low cytotoxicity, amphiphilic chitosan was synthesized and linked with low-molecular weight polyethylenimine (PEI). ...
متن کاملAtomistic simulations of the structure of highly crosslinked sulfonated poly(styrene-co-divinylbenzene) ion exchange resins.
The microscopic structures of highly crosslinked sulfonated poly(styrene-co-divinylbenzene) resins have been modeled by generating atomistic microstructures using stochastic-like algorithms, which are subsequently relaxed using molecular dynamics. Two different generation algorithms have been tested. The relaxation of the microstructures generated by the first algorithm, which is based on a hom...
