摘要： There is provided a novel chain-end functionalized PEO of formulas (I) to (IV) prepared via living anionic polymerization and chain-end functionalization, as well as a simple method of preparing nano-sized transition metal or metal salt particles using the same, which can be readily stabilized even in an aqueous medium. The water-soluble PEO-based polymers having various functional groups (including a drug group such as vitamin and anti-cancer agent) and the process of preparing nano-sized transition metal or metal salt particles using the same can be advantageously used in the development of new materials for drug delivering system and imaging, e.g., a contrast agent and an anti-cancer agent simultaneously.

摘要： The present invention relates to a process for preparing copolymer hydrogels with controlled molecular weights and having both thermo- and pH-responsive properties, wherein the process comprises the steps of (a) providing sulfonamide type styrenic or (meth)acrylamide-based monomers exhibiting different pKa values; (b) providing poly(N-isopropylacrylamide) or crosslinked poly(N-isopropylacrylamide-co-methylene bisacrylamide) hydrogels having thermo-responsive properties; and (c) providing several hydrogels exhibiting pH-sensitive properties and random or block copolymerizations of the sulfonamide type styrenic or (meth)acrylamide-based monomers prepared in step (a) with N-isopropylacrylamide and/or methylene bisacrylamide monomers used in step (b) in a polar or non-polar solvent; wherein said steps (b) and (c) are carried out by controlled/living radical polymerization using alkyl halides as the initiators and the transition metals with phosphine or amine ligands as the catalysts. The present invention also relates to the copolymer hydrogels made by the aforesaid process.

摘要： A new rigid polyvinyl chloride foam is provided which has been improved with respect to the thickness of its non-foamed layer and the surface properties including its tensile strength and compressive strength. The foam can be produced preferably by mixing (per hundred resin) dioctyl phthalate and 4-20 phr of an impact-resistance modifier such as a methyl methacrylate acid-butadiene-styrene copolymer with a composition 100 phr of vinyl chloride resin, 5 phr of processing aid, 2 phr of a heat stabilizer, 0.5 phr of a lubricant, 0.75 phr of a foaming agent and 0.75 phr of boric acid, and then extruding the resulting mixture from a single-screw extruder.

摘要： Disclosed are nano-sized metals and metal salts stabilized by using semi-telechelic and telechelic polymers prepared through living anionic polymerization, and their synthetic methods, and a nanostructure wherein the nano-sized particles are self-assembled by mixing block copolymers and film-casting. The present invention provides a new method for preparing nano-sized particles capable of easily accomplishing nanostructure by merely mixing, especially with block copolymers, and having excellent stability.
