Abstract: An ion exchange resin and a method for preparing the same are provided. An ion exchange resin is formed by a composition, and the composition includes a crosslinking agent and an ionic compound with sulfonate ions. The ionic compound with sulfonate ions is formed by reacting an epoxy resin with an ionic monomer with sulfonate ions or an ionic polymer having sulfonate ions. The ionic monomer and the ionic polymer each has a hydroxyl group or an acid group at the ends. The ionic monomer or the ionic polymer is 40 to 80 parts by weight, and the epoxy resin is 15 to 25 parts by weight, based on 100 parts by weight of the ion exchange resin. An ion exchange resin with a network structure is formed after the ionic compound with sulfonate ions reacts with the crosslinking agent.

Abstract: Disclosed are methods for manufacturing bio-based epoxy resins. The raw materials of the resins include lignin, polyol, solvent, catalyst, acid anhydride, and multi-epoxy compound. The methods of manufacturing the resins include evenly mixing the lignin, the polyol, the catalyst, and the solvent together to form a mixture. The acid anhydride is added to the mixture to process esterification for forming an intermediate product. The multi-epoxy compound is added to the intermediate product to process epoxidation for forming the bio-based epoxy resins. The bio-based epoxy resin has excellent compatibility with the solvent, such that the solvent can be added to the bio-based epoxy resins to form coatings having a tunable solid content. As a result, the coating can be applied to the surfaces of every type of base material.

The display seat can be connected to an external power source or a battery source to establish electrical connection for activating the light emitting diodes. Shallow grooves can be formed in a top portion of the seat body for placement of round or curved articles of display. Beams of light emitting from the light emitting diodes penetrate through the plastic or glass seat body toward the articles of display on the seat body.

Abstract: A data editable statistic calculator having an input device, a memory, a statistic computing unit, and an output device. The input device includes a set of number entry keys for data entry, enabling inputted data to be stored in registers in the memory, so that the user can fetch a specific datum from the registers sequentially with a function key for further editing through the number entry keys. When entering EDIT mode under statistic mode, the user can clearly find out the desired data for editing, and then delete or edit the data. By means of this humanized design, the user can conveniently review the correctness of every inputted data.
