Problems solved by technology

When metal powder or carbon powder is added, it is easy to cause poor transparency and affect the optical properties of the pressure-sensitive adhesive
When polyoxyethylene derivatives are added, the performance of the pressure-sensitive adhesive will be reduced due to the migration of such surfactants to the surface of the pressure-sensitive adhesive

preparation example

[0056] The preparation of preparation example methacrylate polymer (A)

[0057] Put 189.4 parts by weight of butyl acrylate, 10 parts by weight of acrylic acid, and 0.6 parts by weight of hydroxyethyl methacrylate into a four-necked flask equipped with stirring blades, a thermometer, a nitrogen gas inlet tube, and a condenser as a polymerization initiator 0.16 parts by weight of 2,2'-azobisisobutyronitrile, and 466 parts by weight of ethyl acetate as a solvent, after nitrogen gas was introduced for about 30 minutes under gentle stirring, the polymerization reaction was carried out for about 8 hours, and the flask The temperature of the liquid inside was maintained at about 60° C., and after cooling to room temperature, 334 parts by weight of ethyl acetate was added for dilution, thus preparing a polymer (A) mainly composed of acrylate (solid content: 20%). The glass transition temperature of the polymer (A) was -44° C. and the weight average molecular weight was 1,280,000 as m...

Abstract

The invention relates to an antistatic ionic compound, an oligomer thereof, a copolymer thereof and a pressure-sensing agglutinant component thereof, wherein the pressure-sensing agglutinant component contains the ionic compound, the oligomer thereof, the copolymer thereof or the compound thereof containing (methyl) ammonium crylic esters cation and (CF3SO2)2N-anion, so the formed pressure-sensing adhering slice has an excellent antistatic property and a stable adhering property. The invention is suitable for being used in the plastics which easily generate static and the electronic products which have no static, such as a Polaroid, and the like.

Description

technical field [0001] The present invention relates to an antistatic ionic compound, its oligomer, its copolymer, and a pressure-sensitive adhesive composition containing it, especially an antistatic component and an acrylic pressure-sensitive adhesive composition containing it. With excellent adhesion and antistatic properties. Background technique [0002] Pressure-sensitive adhesives (PSAs) are pressure-sensitive adhesives that can glue two different materials together just by contacting pressure. They are widely used and convenient, and have been used in flat-panel display devices. For example, as the back glue of the polarizing plate of the liquid crystal display. [0003] Conventional pressure-sensitive adhesives are composed of organic polymer materials and generally have high insulating properties, so they will generate static electricity when rubbed or peeled off. Therefore, when the polarizing plate is to be bonded to the LCD panel, when the release film used to...
