A film having the low dependency of film transparency on film-forming conditions and thickness, and having superior transparency and rigidity without compromising the original properties of polypropylene film. The film is produced from a polypropylene prepared from a propylene polymer having: (1) a stereoirregularity index mmrr/mmmm of a xylene-insoluble fraction at 20 DEG C within the range of ...

An acid-modified polyolefin is dispersed in water by adding a hydroxy-functional ester made from a polymeric acid and a monoepoxide having from 14 to 46 carbon atoms to the water. Said dispersion is substantially zero-VOC. When a composition of this invention is applied to the surface and cured by baking the article at an elevated temperature, a coating is obtained which improves the adherence of ...
