Multistage preparation of aqueous pressure-sensitive adhesive dispersions for producing self-adhesive articles

Номер: US20120077030A1
Автор: Daniel Wilms, Gerhard Auchter, Matthias Gerst, Michael Gross, Roelof Balk
Принадлежит: BASF SE

Described is a process for preparing an aqueous pressure-sensitive adhesive dispersion from ethylenically unsaturated, free-radically polymerizable monomers. In a first stage, a first polymer is prepared by free-radical emulsion polymerization. In a second stage, an aqueous polymer dispersion is prepared in the presence of the first polymer, where the glass transition temperature calculated for a polymer prepared from the monomers of the second stage is less than −20° C. The monomers of the first stage comprise monomers with acid groups. The polymerization of the first stage takes place at a low pH of less than 5. The acid groups of the first polymer are neutralized during, or before and during, the polymerization of the second stage to an extent such that the pH of the polymer dispersion at the end of the second stage is greater than 5. The aqueous pressure-sensitive adhesive dispersions can be used for producing self-adhesive articles, especially self-adhesive labels and adhesive tapes.

The present invention relates to a non-aqueous dispersant, a color material dispersion liquid and a method for producing the same, a color resin composition and a method for producing the same, a color filter, a liquid crystal display device, and an organic light-emitting display device.Thin image display devices as typified by displays, i.e., flat panel displays, have been released on the market because they are thinner than cathode-ray tube displays and they do not occupy much space in depth. Their market price has decreased year by year with advances in production techniques, resulting in a further increase in demand and a yearly increase in production. Especially, color LCD TVs have almost become the mainstream of TVs. Also in recent years, organic light-emitting display devices such as organic EL displays, which emit light by themselves and thereby have high visibility, have received attention as the next generation of image display devices. In relation to the performance of these image display devices, there is a strong demand for a further increase in image quality, such as an increase in contrast and color reproducibility, and a decrease in power consumption.A color filter is used in these liquid crystal display devices and organic light-emitting display devices. For example, in the case of color LCDs, the ...

Принадлежит: Arkema France SA

The invention relates to the use of low levels of aliphatic short-chain saturated esters to control air void formation in any exothermic polymerization reaction in which the exotherm exceeds the boiling point of the monomer. One such polymerization is the bulk polymerization of one or more monomers having carboxylic acid ester monomers, at a level of at least 10% of total monomer. The aliphatic short-chain saturated esters are used in the polymerization mixture at levels of 0.5 to 10 weight percent, based on the carboxyl-containing monomer. The invention is especially useful in polymerization of methylmethacrylate polymers and copolymers, either neat, or as a polymer composite system.
