Non-bond crosslinked macroporous thermally reversible hydrogels of poly-N-isopropylacrylamide were obtained by copolymerization with the crosslinking agent cyclic octaethylene glycol fumarate, a 29-membered ring, having a polymerizable double bond; t

Simple economical syntheses in good yield of octa-, nona-, and undecaethylene glycols were developed based on a coupling methodology whereby monobenzyl trior tetraethylene glycols were chain-extended either by coupling them together in the presence o

In the new type of non-bond crosslinking where a vinyl macrocycle acts as the crosslinking agent, it is shown that factors affecting threading of polymer chains into macrocyclic rings which lead to crosslinking, such as ring size, ratio of co-monomer

We report here on the fabrication and optimization of composites of conjugated polymer in Sol-Gel and PVA matrices. FTIR spectroscopy as well as other observations show that efficient phase and absorption holograms can be created in the material upon

We describe a method to miorofabricate a light emitting diode (LED) pixel array based on conjugated electroluminescent polymers sandwiched between ITO and aluminum. The method, based on direct photoablation using a 193 nm excimer laser, maintains int
