ABSTRACT:
Opaque pearlescent polymer films, e.g., polypropylene, containing finely dispersed particles of an incompatible polymer e.g., nylon, are improved by blending a polymeric interfacial agent with the film polymer and the incompatible polymer to give a film having the incompatible polymer dispersed in smaller spherical particles and reduced stringness.
