Abstract
An improved process for forming polyamide dispersions in water utilizing carbon dioxide to facilitate dispersion of the polyamide is disclosed. The polyamides are generally below 30,000 or 40,000 g/mole molecular weight when dispersed, but can be chain extended with polyfunctional species such as polyisocyanates after dispersion. The dispersions are useful in coatings, adhesives, and inks. Composites and hybrids of these other polyamides with vinyl polymers are also disclosed and claimed.
