  • Publication number: 20100178497
    Abstract: Disclosed is an adhesive composition which is mainly composed of a polymer obtained by copolymerizing a monomer composition containing styrene, (meth)acrylic acid ester having a cyclic structure and alkyl (meth)acrylate having a chain structure. The monomer composition may additionally contain a bifunctional monomer, thereby improving heat resistance, adhesive strength under high temperature conditions, and alkali resistance, and easiness in stripping of an adhesive composition that has been processed at a high temperature. Consequently, there can be obtained an adhesive composition which has high heat resistance, adhesion strength under high temperature conditions, and alkali resistance, and which can be easily stripped off after the adhesive composition is processed at a high temperature.

  • Patent number: 7745566
    Abstract: The present invention provides methods for purifying polymers. In each embodiment of the invention disclosed herein, a supercritical fluid is contacted with an organic solution that includes a polymer to be purified dissolved in an organic solvent. The supercritical fluid extracts the organic solvent from the organic solution. Impurities such as residual monomers and process solvents are removed with the organic solvent and supercritical fluid, thereby purifying the polymer. The methods of the invention are particularly suitable for use in the purification of biodegradable polymers for use in pharmaceutical applications.

  • Publication number: 20090170726
    Abstract: A curable composition and a process for using the curable composition within a grating-coupled waveguide (GCW) sensor are disclosed. The composition can be used for facile replication of optical components, specifically those used in a label-independent detection system where operation of the waveguide is dependent on the detailed formation of micro and nano size patterns. The photo or electron beam curable composition has low viscosity (?500 cPs) and cures to an optically clear material with high glass transition temperature (?70° C.), low shrinkage on cure, low outgassing, and low extractables.

  • Publication number: 20090102280
    Abstract: The present invention is directed generally to track segments for track vehicles and, more specifically, to a track segment having an ethylene propylene diene monomer (EP(D)M) rubber based backer, and a method of making. In one embodiment, the track segment includes an EP(D)M rubber based backer including a rubber compound having 100 phr EP(D)M rubber wherein the diene component is optionally present, a peroxide curing agent, and one or more acrylic and/or methacrylic coagents. The track segment further includes a track pad and a track body. The track pad and backer cooperate with the track body to define the track segment for use in a track for a track vehicle. The EP(D)M rubber based compound provides a desirable balance of low heat build-up under heavy dynamic cyclic compression conditions, and also has a desirable load carrying capability, high heat resistance, and good cut/tear strength in hot climates.
