A novel, Y-type polyurethane containing 1- 2,4-dioxyethoxy phenyl-2-{5- 2,2-dicyanovinyl -2-thiophenyl}ethenes as nonlinear optical chromophores present within the polymer backbone, was prepared and characterized.
In addition, a series of polyaspartimides containing a naphthalene unit in the polymer backbone were prepared by the polyaddition of this bismaleimide and various diamines via a Michael-type addition in m-cresol with glacial acetic acid as a catalyst.
Starting from 2,6-bis- 3-octylthiophene-2yl -pyridine 2,6-bis- 3-octylthiophene-2yl -pyridine 2,6-bis- 3-octylthiophene-2yl -pyridine 2,6-bis- 3-octylthiophene-2yl -pyridine 2,6-bis- 3-octylthiophene-2yl -pyridine 2,6-bis- 3-octylthiophene-2yl -pyridine
Other analogs with different carbon frame at C4 position which is corresponding to the sphingoid backbone were prepared from 3-cyclopentanecarbonyl-4- 1-t-butyldimethylsilyloxybut-2-enyl -oxazolidin-2-one and straight and cyclic alkenes by cross metathesis.
PLLA comb polymers on PHEMA backbone were prepared by ring-opening polymerization.
Poly l-lactide) (Poly l-lactideymers on PLLA(hydroxyethyl methacombate) (polymersackbone were polyared on thydroxyethylf clay layers by a comethacrylate in situ atom transfer radical PHEMAerization (ATRP) and ring-opening polymerization.
A series of main-chain polyurethanes containing sulfonyl-based NLO chromophores in the polymer backbone were prepared, the subtle structure of the chromophore moieties could be easily modified to adjust the property of the resultant polymers.
By combining different hydrophobic moieties and hydrophilic polymer backbones, various self-assembled nanoparticles were prepared, and their in vivo distributions in tumor-bearing mice were studied by radionuclide imaging.
Hyper-branched polymers comprised of dense polyoxyethylene (POE) comb graft and poly methyl methacrylate) (PMMA) backbone are prepared with a well-defined chemical structure and the gas transportation properties are investigated.
Aromatic polyamides (N-a, a = I III) containing disulfide bonds and pyridine rings in the polymer backbone are prepared by condensation of diacid, 6,6′-dithiodinicotinic acid (N) and the corresponding alkyl diamine (a = I III: NH2- CH2)n-NH2, n = 4, 6, 12) with interfacial polymerization technique.
