Abstract
Aqueous dispersions of olefin resins having a low film-forming temperature can be continuously produced by homogeneously mixing a mixture composed of olefin resin, partially saponified polyvinyl alcohol and water by means of an extruder having a multi-screw, and extruding the resulting dispersion. If partially saponified polyvinyl alcohol in which residual acetic acid groups are blocked is used, the film-forming temperature thereof is effectively lowered.
