OPAQUE PEARL LIKE FILM CONTAINING POLYMER BLEND IMPARTING IMPROVED DISPERSION OF NON-COMPATIBLE POLYMER PHASE AND ITS PRODUCTION

摘要

Opaque pearlescent polymer films, e.g., polypropylene, containing finely dispersed particles of an incompatible polymer, e.g., nylon, are improved by blending a polymer compatible with the polymer forming continuous film phase to alter its melt rheology and to cause dispersion of the incompatible polymer in small spherical particles with reduced stringiness.
