Abstract: Disclosed is a method for packaging an LED by a thermoplastic copolymer. The copolymer is polymerized by 100 parts by weight of an acrylic ester, 0.1 to 30 parts by weight of a hydrogen bond monomer, and 0.1 to 70 parts by weight of a bulky monomer. The copolymer has transparency greater than 90%, thermal resistance greater than 130° C., and moisture absorption less than 0.5 wt %, such that the copolymer may be applied as packaging material for a light emitting device.

Abstract: An Internet advertising system is disclosed. A commercial project database stores a commercial, a questionnaire related to the commercial and a predetermined answer to the questionnaire. A user database stores a cellular phone number correlated to a user. A server is arranged to transmit the commercial and the questionnaire related to the commercial to a user equipment used by the user via the Internet network. An inputted answer from the user equipment via the Internet network is received and verified. The server transmits an authentication code via a cellular phone network based on the cellular phone number. An inputted code from the user equipment via the Internet network is verified for consistence.

Abstract: A mold release agent of polybenzoxazine is used in an imprinting process. With the novel mold release agent used, a surface energy of a template is greatly reduced, so that an excel lent imprinted image is obtained. Besides, the mold release agent is totally resolved in a solution with no pollution produced. In short, the present invention has a high stability and a low cost with easy-obtained source materials.

Abstract: The present invention is directed to a technique for enhancing an ionic conductivity of a polymer electrolyte composition composed of a matrix polymer containing at its backbone or side chain a Lewis base functional group; and a metal salt containing a metal ion and a counter ion; and optionally a plasticizer by mixing a promoter polymer therein. The promoter polymer contains a hydrogen-bond-forming functional group. The hydrogen-bond-forming functional group forms a hydrogen bond with said Lewis base functional group, creating an enhanced basicity of said Lewis base functional group and/or a reduced crystallinity of said matrix polymer, so that said ionic conductivity is improved.

Abstract: The present invention provides a functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer which is obtained from the following layers by emulsion graftlinking polymerization: an inner layer comprising polybutadiene or an aromatic vinyl compound-butadiene copolymer; a middle layer comprising an aromatic vinyl compound-an alkyl acrylate copolymer; and an outer layer comprising an alkyl acrylate-a functional group-containing vinyl compound copolymer. The functional group-containing alkyl acrylate-butadiene-aromatic vinyl compound copolymer can be incorporated into a PC/PBT alloy as an impact modifier, thus the impact strength of the modified alloy composition at room temperature and low temperatures can be increased effectively.

Abstract: Epoxy resins are prepared by dehydrohalogenating the reaction product of a polyhydric phenol with an excess of an epihalohydrin in the presence of a quaternary ammonium compound wherein prior to dehydrohalogenation, the excess epihalohydrin is removed and an organic solvent is added and at least a portion of the dehydrohalogenation is conducted in the presence of added quantities of a quaternary ammonium compound.

Abstract: Occluded organic solvent is removed from bisphenol crystals by placing in water maintained at a temperature sufficient to form a molten water-bisphenol phase, holding at that temperature for a time sufficient to transfer the organic solvent to the water phase, flash distilling the organic solvent, cooling molten water-bisphenol phase to produce crystallization and thereafter recovering the bisphenol.

Abstract: A method of purifying bisphenols by (1) crystallizing the crude bis from a single liquid phase containing water, bis and an organic solvent, (2) stripping the remaining mother liquor (containing the impurities) of solvent and water, and (3) mixing it with phenol, (4) contacting the mixture of phenol and mother liquor with a cation exchange resin to convert the impurity to the desired product, (5) stripping the phenol and (6) recycling the remainder to the initial crystallizing step.
