20080275182 | Method For Producing An Aqueous Polyamide Dispersion - A process for preparing an aqueous polyamide dispersion by enzyme-catalyzed polycondensation reaction of a diamine compound and a dicarboxylic acid compound in aqueous medium. | 11-06-2008 |
20080319129 | Preparing Aqueous Dispersion of Crystalline and Amorphous Polyesters - Processes for generating aqueous dispersions for use in the emulsion/aggregation technique, by combining crystalline polyester resin, amorphous polyester resin and water, heating and agitating the mixture and generating an aqueous dispersion containing both crystalline polyester resin particles and amorphous polyester resin particles. | 12-25-2008 |
20100056718 | PROCESS FOR PRODUCING POLYAMIC ACID SOLUTION AND POLYAMIC ACID SOLUTION - In a first step, a diamine is reacted with a molar excess of a tetracarboxylic dianhydride in a solvent containing more than ⅓ mole of water per mole of the tetracarboxylic dianhydride, whereby preparing a polyamic acid solution. Subsequently, in a second step, a diamine and/or a tetracarboxylic dianhydride are added to the polyamic acid solution obtained in the first step so that the molar amount of the diamine component is substantially equal to the molar amount of the tetracarboxylic acid component, and then the diamine and the tetracarboxylic dianhydride are reacted, whereby preparing a polyamic acid solution. By this process, a polyamic acid solution having a high concentration and a low viscosity may be reproducibly and reliably produced, while controlling the molecular weight of the polyamic acid to a predetermined low level. | 03-04-2010 |
