Poly ethylene glycol acrylate

Degradable difunctional poly(ethylene glycol) acrylates, (1), were prepared by Harris [1] and then photolyticaUy converted into hydrogels and used in drug delivery systems. [Pg.261]

Curcumin shows very interesting therapeutic properties in the fields of cancer, AIDS, or inflammation, but its use is limited by a low aqueous solubility and poor bioavailability. Nanocurc is a dispersion of curcumin, in micelles of synthetic block copolymer of N-isopropylacrylamide, N-vinylpyrrolidone, and poly(ethylene glycol)acrylate. Nanocurc is a water-soluble version of curcumin, with increased bioavailability and activity against tumor growth and metastases. The in vivo studies suggest that Nanocurc allows curcumin to cross the blood-brain barrier and exert an activity against inflammatory damages in the brain associated with Alzheimer s disease. ...

Single lithium ion conducting polymer electrolytes have been prepared by the copolymerizahon of hthium(4-styrenesulfonyl)(trifluoromethanesulfonyl) imide and methoxy-poly(ethylene glycol) acrylate [117]. The highest ionic conduchvihes for the copolymer electrolytes are 7.6 x 10 S cm at 25 °C and then grow to reach 10 " S cm at 60 °C, at a raho of ethylene oxide to Li+ of 20.5. [Pg.358]

Surface graft polymerization of poly(ethylene glycol) acrylate was used to modify the surface of PDMS. Templates with channels were formed from this material and sol-gel chemistry was used to form amino-silane doped xerogel microarrays. These structures were then used to release nitric oxide at various rates, by control of micropattern dimensions, type and concentration of the amino-silane, and so on. This method parallels the use of polymers in controlled drug-delivery systems. ... [Pg.128]

This assembly chemistry is only limited by the preparation of an appropriate amphiphilic or hydrophobic diblock copolymer. With the structure and chemical composition of the resultant nanoparticles readily tunable using a wide range of block copolymers that are synthetically available. A broad range of polymers have been utilized as the core hydrophobic domain of shell-crosslinked nanoparticles and include styrene, isoprene, butadiene, caprolactone, poly (ethylene oxide), acrylates, methacrylate and acrylamides. Monomers that have been used to prepare the hydrophilic water-soluble domain include, among others, poly(ethylene glycol), acrylic acid, 4-vinylpyridine, (meth)acrylic acid, 2-dimethylaminoethyl methacrylate and Wisopropylacrylamide.

Different effects can be expected from different block copolymers. For example, PMMA and poly(ethylene glycol acrylate) can form a block copolymer. Although it has a homogeneous phase structure, microphase separation can result when lithium salt is added to form the electrolyte [1]. [Pg.371]
