AQUEOUS DISPERSION AND PROCESS FOR PREPARATION THEREOF
An aqueous dispersion comprises (i) a hydrophobic thermoplastic polymer, (ii) a water-insoluble thermoplastic polymer containing a carboxylic acid salt group bonded to the polymer chain at a concentration of 0.1 to 5 milliequivalents as -COO- per gram of the polymer, (iii) water and, if necessary, (...

Summary: | An aqueous dispersion comprises (i) a hydrophobic thermoplastic polymer, (ii) a water-insoluble thermoplastic polymer containing a carboxylic acid salt group bonded to the polymer chain at a concentration of 0.1 to 5 milliequivalents as -COO- per gram of the polymer, (iii) water and, if necessary, (iv) at least one member selected from the group consisting of anionic surface active agents, non-ionic surface active agents, organic solvents and oils, said aqueous dispersion being apparently solid and having a water content of 0.5 to 3% by weight and an electric resistance lower than 10 OMEGA -cm and also having such a property that when water is added to the dispersion, solids are uniformly dispersed as fine particles in the aqueous phase. |
