The present invention relates to a diisocynate compound having anhydrosugar alcohol core and a preparation method therefor and, more specifically, to a diisocynate compound having anhydrosugar alcohol core and a preparation method therefor, wherein the diisocynate compound is prepared through a reaction with a nitrile compound, a hydrogenation reaction, and an end-group substitution reaction while a recyclable, plant-based anhydrosugar alcohol or anhydrosugar alcohol-alkylene glycol is used as a raw material, and the diisocynate compound can be utilized in various fields, such as soft or hard polyurethane expanded foams, molded foams, coating, adhesives or glues, fibers, and polymer synthesis.

Diisocyanate compound having anhydrosugar alcohol core and preparation method therefor

The present invention relates to a polyol composition comprising anhydrosugar alcohols and an anhydrosugar alcohol polymer and, more specifically, to a polyol composition comprising a monoanhydrosugar alcohol, a dianhydrosugar alcohol, and a polymer of a monoanhydrosugar alcohol and/or a dianhydrosugar alcohol, the polyol composition being usable in various fields since the physical property conditions of the composition, such as number average molecular weight (Mn), polydispersity index (PDI) and hydroxyl value, satisfy specific levels, and, particularly, being capable of remarkably improving the physical properties of a polyurethane, such as tensile strength and elongation, when used as a polyurethane chain extender.

Polyol composition comprising anhydrosugar alcohols and anhydrosugar alcohol polymer

The present invention relates to a plasticizer composition and a preparation method therefor and, more specifically, to a plasticizer composition, which contains an anhydrosugar alcohol monoester, an anhydrosugar alcohol diester, and a sugar alcohol ester at a specific content ratio and has improved plasticity and excellent storage stability, and to a preparation method therefor.

Plasticizer composition and preparation method therefor

A portable multi-kit assembly for storing electronic parts according to the present invention includes a base in which a plurality of accommodation portions configured to accommodate electronic parts is formed. The plurality of accommodation portions includes a first accommodation portion configured to accommodate a first part. The first part is fastened to the first accommodation portion, and is coupled to a first coupling kit having a shape corresponding to that of the first accommodation portion and accommodated in the first accommodation portion. A grip portion is foiled on the first coupling kit, and allows the first part to be withdrawn from or retracted into the base in such a manner that the grip portion is pushed with a finger.

Portable multi-kit assembly for storing electronic parts

Provided is a removable storage system including: a data storage device configured to store a plurality of files including a first file and a second file; a host interface configured to receive, from a host, a pattern matching request including pattern information and file information regarding the plurality of files, and transmit, to the host, a result of pattern matching regarding the plurality of files; and a pattern matching accelerator configured to perform the pattern matching in response to the pattern matching request, wherein the pattern matching accelerator includes a scan engine configured to scan data based on a pattern, and a scheduler configured to control the scan engine to stop scanning the first file and start scanning the second file.

Storage system and operating method thereof

Disclosed herein is an electrode assembly including 2n (n being a natural number equal to or greater than 1) polar bodies which are stacked.
