Abstract
A thermosetting aqueous-type emulsion of nadimide is disclosed. The emulsion comprises 1-70% by weight of an alkenyl-substituted nadimide, 0.1-20% by weight of protective colloid and/or surface-active agent and balance water. The emulsion is especially useful for making a paint, a coating material or an adhesive because the emulsion can easily be cured only by heating without forming any undesirable organic pollutants. In the past, various resins have been used together with organic solvents. However, because of the recent worldwide concern over the influence of organic solvents to pollution of the aerospace and underground environments, non-use or reduced-use of organic solvents is actively desired. Accordingly, developments of aqueous solution or aqueous-type emulsion of resins are desired. Until now there is no aqueous-type emulsion of a monomer of highly heat resistant polyimide.
