Vinylidene chloride interpolymer possessing improved extrudability

摘要

A process for improving the extrudability of a vinylidene chloride interpolymer pellet. A vinylidene chloride interpolymer pellet displaying a first endotherm, as determined by differential scanning calorimetry according to American Society of Testing and Materials Test Method D-3417, below 75 DEG Celsius is exposed to a temperature above about 55 DEG Celsius for a length of time sufficient to raise said first endotherm to 75 DEG Celsius or above. Pellets treated in such a manner possess improved extrudability.
