Low temperature curable polyimide resin and method of preparing the same

Номер: US20120016076A1
Автор: Dong Hyun Oh, Kyung Jun Kim, Sang Woo Kim, Se Jin Shin
Принадлежит: LG Chem Ltd

In a method for preparing a polyimide resin by reacting diamine and dianhydride, the polyimide resin is polymerized under the presence of a solvent having a boiling point ranging from 130° C. to 180° C. so as to be curable at a low temperature ranging from 150° C. to 250° C. Because the polyimide is curable even at a low temperature, when the polyimide resin is used as an electronic material, damage to equipment due to an otherwise high temperature process can be minimized, and in addition, the polyimide resin can be extensively used as an electronic material such as for a plastic substrate, or the like.

A method is described for the production of a dispersion, especially a coating or sealing compound, having a viscosity of less than about 30,000 mPas, whose viscosity increases to more than 50,000 mPas or that becomes firm as a result of its application, whereby a shear-thickening additive is added to a precursor composition of the dispersion at a shear rate that does not activate the shear-thickening additive. Consequently, it is possible to formulate dispersions, especially sealing and/or coating compounds, in such a way that they have a low viscosity for storage and processing, and only at the time of the use of the dispersion is the final viscosity set by suitable equipment. 1. A method for the production of a dispersion having a viscosity of less than about 30 ,000 mPas , whose viscosity increases to more than about 40 ,000 mPas as a result of its application , comprising:adding a shear-thickening additive to a precursor composition of the dispersion at a shear rate that does not activate the shear-thickening additive.2.
