Abstract:
The invention relates to moulded bodies with a decorative optical effect. Said bodies consist of core-shell particles, whose shell forms a matrix and whose core is essentially solid and has a substantially mono-disperse size distribution, whereby the refractive indices of the core material and the shell material are different. The moulded bodies are characterised in that they can be obtained by the following method: the core-shell particles are heated to a temperature, at which the shell is fusible and the fusible core-shell particles are subjected to a mechanical force.
Abstract:
Sensors for determining the presence and concentration of bio-molecules in a biological sample are provided in the form of polymer brushes, which comprise a substrate having a surface that is modified with a water-dispersible or water-soluble polymer segment having functional groups that bind probes. The method of synthesis of such sensors preferably includes use of controlled free radical polymerization techniques which allows for controlled architecture polymers to modify the surface of the substrate. In this manner functional groups in the polymer chain are removed from the surface, which allows for solution chemistry to be more realistically reproduced with the benefits of a solid bound probe.

The invention relates to surface modified supporting materials for binding biological materials, in addition to a method for the production and the use thereof in the isolation and purification of nucleic acids, especially plasmid DNA. The inventive supporting materials are characterized by a polymer layer on the surface thereof which is comprised of negatively charged groups.
Abstract:
The present invention provides an optically clear, hydrophilic coating upon the surface of a silicone medical device by sequentially subjecting the surface of the lens to plasma polymerization reaction in a hydrocarbon atmosphere to form a carbon layer, and then graft polymerizing a mixture of monomers comprising hydrophilic monomers onto the carbon layer. The invention is especially useful for forming a biocompatible coating on silicone hydrogel contact lenses.
Abstract:
A method of making polymer-coated pigment particles, involving the steps of providing a plurality of pigment particles, each of which has an outer surface coated with a layer of material that operates as a nucleus for initiating polymerization on the outer surface of each of the pigment particles. The pigment particles are mixed with a reaction mixture containing a solvent and a monomer material, wherein the layer of material coating each of the pigment particles causes the monomer material to polymerize on the outer surface of substantially each of the pigment particles to form a polymer coating thereon.
Abstract:
The invention concerns a method for making composites by electrochemical polymer or copolymer coating of a carbon-based support which consists in using a reaction system comprising (a) at least a monomer capable of forming a polymer on said support, (b) an aprotic solvent and (c) an electrolyte providing the resulting organic medium with electric sufficient conductivity for conducting therein electrolysis, whereby the carbon support permanently forms the cathode, by applying a potential or an electric current bringing the reaction system into the passivation zone corresponding to the first inhibition peak detected in the voltampere-tester, so as to form a polymer grafted on said support.
Abstract:
A composite electrolyte comprises (a) surface modified fumed silica filler, wherein the surface modified fumed silica comprises polymerizable groups on the surface thereof, the polymerizable groups being bonded to each other such that the surface modified fumed silica filler is crosslinked in a three-dimensional structure; (b) a dissociable lithium salt; and (c) a bulk medium which contains the surface modified fumed silica filler and the dissociable lithium salt. An electrochemical cell comprises an anode, a cathode, and a composite electrolyte dispersed between the anode and cathode.
Abstract:
Homogeneous, particulate composites are provided, of about 75 - 99.5 weight percent ultrahigh molecular weight polyethylene (UHMWPE) and about 0.5 - 25 weight percent of at least one filler compound, and wherein the composites have a surface area of at least about 4 m2/g. The particulate UHMWPE is also provided without the filler. Dense, load-bearing articles of these materials are formed by cold-pressing and free-sintering procedures. Cold-pressable, free-sinterable blends of commercial UHMWPE containing at least 25 weight percent of the composites or unfilled UHMWPE of the invention are also provided.
