ABSTRACT:
The invention relates to a method and an apparatus for continuously taking a sample from a discharge system of a polymerization reactor having a discontinuously opening discharge valve connecting the polymerization reactor to a product tube leading into a solid-constituent separation system. A sampling means having a closing valve of an on/off type is connected to the product tube. The closing valve closes for the period of a pressure wave occurring when the discharge valve opens, and opens after the pressure wave. A buffer container connected to an analyzer is provided with a sufficient volume to maintain the continuity of the sample flow when the closing valve is closed.
