ABSTRACT:
A process for continuously monitoring and controlling product film quality from a polymer production unit and for automatically separating acceptable and unacceptable polymer product includes the steps of continuously formulating a solid particulate polymer product in the polymer production unit; withdrawing a product sample and preparing a film from the product sample; analyzing the film properties; continuously delivering the product remaining after product sampling to a residence holding device; and providing a signal representative of the film analysis so as to divert acceptable product in the holding device to product storage or unacceptable product to a by-product delivery line.
