Abstract
The present invention relates to the monitoring of polymers during their processing by the determination of optical scattering properties. According to one aspect of the invention, there is provided a monitoring system for a vessel for polymer processing and the like, comprising a monitoring cell for measuring the optical properties of the contents of the vessel, a feed path and a return path both connecting the cell to the vessel, and a pump connected in the feed or return path. According to another aspect of the invention there is provided a monitoring cell for measuring the optical properties of the contents of the cell, including a source for generating a laser beam through the cell, and a detector for detecting light scattered from the laser beam, preferably a linear camera and an optical system for focusing scattered light thereon.
